Polyethylene 化学特性,用途語,生産方法

  • 定義 本品は、エチレンの重合体であり、次の化学式で表される。
  • 解説 略称PE.エテンの重合体で,一般式"で表される.一般に重合体は,酸,アルカリ,溶剤に耐えるが,炭化水素,ハロゲン置換炭化水素には高温で溶解する.電気絶縁性,耐水性,耐寒性がすぐれ,押出し,射出,吹込み,真空成形などの成形加工もきわめて容易なので,代表的な熱可塑性樹脂として各種容器,電線被覆,パイプ,繊維,包装材料などに多く用いられる.ポリエチレンの工業的製法としては,高圧法,中圧法,および低圧法がある.(1)高圧法(図(a))では,まずエテンを100~300 MPa に加圧し,酸素,有機過酸化物などの開始剤を加え100~200 ℃ に加熱後,冷却管つきの管状重合反応器に送り込む.重合の進行に伴い反応熱(106 kJ mol-1,25 ℃)のために反応系は150~300 ℃ に昇温する.反応器を出てくる混合物は減圧後,ポリマーとワックス状の低分子量体を除去し,未反応エテンは再使用される.水などの溶媒を用いる懸濁重合法もある.このような高圧法で得るポリマーは,0.915~0.935 g cm-3 の低密度ポリエチレンである.(2)中圧法(数 MPa)には,8% 程度の酸化モリブデンをアルミナに担持した触媒を用いる標準法と,酸化クロムをアルミナに担持した触媒を用いるフィリップス法(図(b))とがある.後者の場合,重合は不活性溶媒中で行われ,重合温度が130 ℃ 以上ではポリマーが可溶なため溶液重合に,また130 ℃ 以下では不溶なため懸濁重合となる.重合終了後,未反応のエテンは,気液分離器で分離され再使用される.一方,ポリマーを含む液相部は熱溶媒で希釈され,沈殿触媒を除去後,溶媒を分離する.ポリマーは押出成形を経て製品となる.なお,溶媒を用いない気相重合も可能である.このような中圧法で得られるポリマーは,0.960~0.970 g cm-3 の高密度ポリエチレンである.(3)低圧法(常圧)(図(c))では,チーグラー触媒が用いられ,炭化水素溶媒中,常圧付近60~100 ℃ で懸濁重合が行われる.重合終了後,アルコールなどを用いて触媒を分解分離し,ポリマーを濾別する.このような低圧法で得られるポリマーは,0.940~0.965 g cm-3 の高密度ポリエチレンである.(4)以上の方法のほか,ユニオンカーバイド社の,0.7~2 MPa,60~100 ℃ の条件下で気相重合により触媒分離を必要としない(無脱灰)低密度ポリエチレンの製造法(図(d))がある.[CAS 9002-88-4]"

  • 化学的特性

    Chemical and physical properties are markedly affected by increasing density, which is affected by the shape and spacing of the molecular chain. Low-density materials have highly branched and widely spaced chains, whereas high-density materials have comparatively straight and closely aligned chains. Low-density polyethylene (0.926–0.9409 g/cm3) is soluble in organic solvents at temperatures higher than 200°F. It is insoluble at room temperature. High-density polyethylene (0.041–0.965 g/cm3) is hydrophobic, permeable to gas, and has high electrical resistivity.
    Low molecular weight polyethylenes have excellent electrical resistance and resistance to water and to most chemicals. Medium molecular weight polymers are waxes miscible with paraffin wax, and polyethylene polymers whose molecular weights are higher than 10,000 are the familiar tough and strong resins that are flexible or stiff. By varying the catalyst and methods of polymerization, properties such as density, crystallinity, molecular weight, and polydispersity can be regulated over wide ranges. Polymers with densities ranging from approximately 0.910 to 0.925 g/cm3 are low-density polyethylenes; those with densities ranging from 0.926 to 0.940 g/cm3 are medium-density polyethylenes; and those with densities ranging from 0.941 to 0.965 g/cm3 and higher are high-density polyethylenes.


    As the crystallinity or density increases, the products generally become stiffer and stronger and have a high softening temperature and high resistance to penetration by liquids and gases. At the same time, they lose some of their resistance to tear and environmental stress cracking.
    High-density PE (HDPE) is a chemically pure, porous plastic implant material that can perform supportive functions. The material has good tissue biocompatibility and permits ingrowth of connective tissue with related vascularization. The material is being used more frequently in nasal surgery.
    Polyethylene can be cross-linked by irradiation (electron beam, gamma, or X radiation) or by free radical catalysts such as peroxides.

  • 定義

    Polyethylene is a flexible waxy translucentpolyalkene thermoplastic made in avariety of ways producing a polymerof varying characteristics. In the ICIprocess, ethene containing a trace of oxygen is subjected to a pressure inexcess of 1500 atmospheres and atemperature of 200°C. Low-densitypolyethene (r.d. 0.92) has a formulaweight between 50 000 and 300 000,softening at a temperature around110°C, while the high-density polythene(r.d. 0.945–0.96) has a formulaweight up to 3 000 000, softeningaround 130°C. The low-density polymeris less crystalline, being more atactic.Polyethene is used as aninsulator; it is acid resistant and iseasily moulded and blown.
    Polyethylene is a water-repellent, white, tough, leathery, thermoplastic resin very similar in appearance to paraffin wax. Properties vary from a viscous liquid at low molecular weights to a hard waxlike substance at high molecular weights. It is used as a coating for glass bottles and fiberglass fabrics (special treatments for glass are required to obtain good adhesion between polyethylene and glass) and is also used as an injection-molding material for ceramics.
    In the polymerization process, the double bond connecting the carbon atoms is broken. Under the right conditions, these bonds reform with other ethylene molecules to form long molecular chains. Ethylene copolymers, EVA, and EEA are made by the polymerization of ethylene units with randomly distributed comonomer groups, such as vinyl acetate (VA) and ethyl acrylate (EA).

  • 使用

    Polyethylene (PE) is a thermoplastic polymer consisting of long hydrocarbon chains. PE is used in a number of applications including flexible film packaging produced by the blown film process. Polyethylene is used to regulate viscosity, suspension properties, and general stability in cosmetic formulations. Typical applications included specialty injection molded parts, in these fields Polyethylene has a wide range of uses:
    Injection and blow molded toys, housewares and lids.
    Injection molded car seats, mower parts and pails.
    Injection molded, thin-walled containers and housewares.
    Hot melt coating for paper, additive in cast moldings, candles, oil-based inks and hot melt adhesives.
    Additive to unsaturated polyesters, epoxides and other polymers to impart the unique properties of UHMWPE. Used in industrial parts, coatings and wear surfaces at 10-40 wt. %.
    Film applications having good drawdown and toughness.
    Mold release additive, lubricant in rubber processing, extrusion and calendering aid for PVC and dispersing aid for color concentrates.
    Bearings, gears, bushings and other moving parts.
    Laboratory tubing; in making prostheses; electrical insulation; packaging materials; kitchenware; tank and pipe linings; paper coatings; textile stiffeners.
    polyethylene is used to regulate viscosity, suspension properties, and general stability in cosmetic formulations. It is derived from petroleum gas or dehydration of alcohol.

  • 工業用途

    Polyethylene thermoplastic resins include lowdensity polyethylenes (LDPE), linear low-density polyethylenes (LLDPE), high-density polyethylenes (HDPE), and ethylene copolymers, such as ethylene-vinyl acetate (EVA) and ethylene- ethyl acrylate (EEA), and ultrahighmolecular- weight polyethylenes (UHMWPE). The basic properties of polyethylenes can be modified with a broad range of fillers, reinforcements, and chemical modifiers, such as thermal stabilizers, colorants, flame retardants, and blowing agents. Major application areas for polyethylenes are packaging, industrial containers, automotive, materials handling, consumer products, medical products, wire and cable insulation, furniture, housewares, toys, and novelties.
    LDPE, the first of the polyethylenes to be developed, has good toughness, flexibility, low-temperature impact resistance, clarity in film form, and relatively low heat resistance. Like the higher-density grades, LDPE has good resistance to chemical attack.
    One of the fastest-growing plastics is linear LLDPE, used mainly in film applications but also suitable for injection, rotational, and blow molding. Properties of LLDPE are different from those of conventional LDPE and HDPE in that impact, tear, and heat-seal strengths and environmental stress-crack resistance of LLDPE are significantly higher. Major uses at present are grocery bags, industrial trash bags, liners, and heavy-duty shipping bags for such products as plastic resin pellets.
    Rigidity and tensile strength of the HDPE resins are considerably higher than those properties in the low- and medium-density materials. Impact strength is slightly lower, as is to be expected in a stiffer material, but values are high, especially at low temperatures, compared with those of many other thermoplastics.
    HDPE resins are available with broad, intermediate, and narrow molecular-weight distribution, which provides a selection to meet specific performance requirements. As with the other polyethylene grades, very-high-molecular- weight copolymers of HDPE resins are available with improved resistance to stress cracking.
    Applications of HDPE range from film products to large, blow-molded industrial containers. The largest market area is in blowmolded containers for packaging milk, fruit juices, water, detergents, and household and industrial liquid products. Other major uses include high-quality, injection-molded housewares, industrial pails, food containers, and tote boxes; extruded water and gas-distribution pipe, and wire insulation; and structural-foam housings. HDPE resins are also used to rotationally mold large, complex-shaped products such as fuel tanks, trash containers, dump carts, pallets, agricultural tanks, highway barriers, and water and waste tanks for recreational vehicles.

  • 調製方法

    Linear PE is produced by a low-pressure solution or gasphase process that is initiated by a variety of transition metal catalysts. The most common catalysts are Ziegler titanium compounds with aluminum alkyls and Phillips chromium oxide-based catalysts. The gas-phase and slurry processes are used to produce high molecular weight, high-density (HMW-HDPE) products. The highest density linear PEs can be made from an α-olefin comonomer, typically octene for the solution process and butene or hexene for the gas-phase process. Linear PE does not have long-chain branches and is therefore more crystalline. The short-chain branches found in linear PE serve as tie molecules, which give the higher α -olefin copolymers improved puncture and tear properties. Included in the linear PE family are ultra-low-density PE (ULDPE), LLDPE, and HDPE.
    HDPE’s main use is in blow-molded products such as milk bottles, packaging containers, drums, car fuel tanks, toys, and houseware. Film and sheet are widely used in wrappings, refuse sacks, carrier bags, and industrial liners. Injection molding products include crates, pallets, packaging containers, houseware, and toys. Extrusion grades are used in pipes, conduit, wire coating, and cable insulation.
    LLDPE is a thermoplastic that in many applications replaces its predecessor, low-density polyethylene (LDPE), or is used in blends with LDPE. In particular, LDPE’s shortchain branching gives it higher tensile strength, puncture, and anti-tear properties, making it especially suitable for film applications.

  • 农业用途 LDPE is short for low density polyethylene. LDPE sheets are used for lining jute bags in which fertilizers are stored. LDPE acts as a waterproofing material.
  • 安全性プロファイル Questionable carcinogen with experimental tumorigenic data by implant. Reacts violently with F2. When heated to decomposition it emits acrid smoke and irritating fumes.
  • Carcinogenicity IARC reports that data available do not allow the evaluation of carcinogenicity of ethylene in humans. Rats exposed to ethylene by inhalation show no increase in tumor incidence.
  • 純化方法 Crystallise it from thiophen-free *benzene and dry it over P2O5 under vacuum.
