ВИНИЛИДЕН ХЛОРИД ЛАТЕКС

Химические свойства

solid

Использование

PVDC has a number of applications, including molding resins, extrusion resins, multilayer film, rigid barriers, containers, lacquer resin, vinylidene chloride copolymer latex and foams, resins for solvent coating, lattices for coating, and pipes for chemical processing.

Методы производства

PVDC polymerizes by both ionic and free-radical reactions. Free-radical polymerization of PVDC may be by solution, slurry, suspension, and emulsion methods. In copolymerization, usually one component is introduced to improve the processability or solubility of the polymer; others are added to modify specific properties. Properties modified by copolymerization depend on the content of components (structure, amounts, and types).

Промышленное использование

Because of its relatively low solubility anddecomposition temperature, Vinylidene Chloride Latex is widely used in the form of copolymerswith other vinyl monomers, such as vinyl chloride.The copolymers are employed as packagingfilm, rigid pipe, and as filaments for upholsteryand window screens.
