Uses

3-(Methacryloyloxy)propyltrimethoxysilane (MPS) acts as a functional comonomer, which is used to prepare polystyrene latex having silanol by emulsion polymerization. It is used in the preparation of polymers in association with other monomers like vinyl acetate, acrylic acid and methyl acrylic acid used in coating, adhesive and sealing agents, which provides excellent adhesion and durability. The composite materials made from unsaturated polyester by using MPS improve mechanical property.

General Description

3-(Trimethoxysilyl)propyl methacrylate (TMSPMA) is a hydrophobic monomer. The presence of an additional functional group of acrylate facilitates TMSPMA for grafting polymerization on plastic surfaces. 3-(Trimethoxysilyl)propyl methacrylate undergoes first-order kinetic polymerization to form polyTMSPMA, which is a moisture stable polymer.

A magnetic stir bar was placed into a 100-mL round-bottomed flask (Schlenk tube) equipped with a two-way stopper. Add 0.24 g (0.75 mmol) of bismuth trichloride (BiCl3) to the flask. The flask was sealed with a septum and nitrogen displacement was performed. Subsequently, 21.9 g (248 mmol) of methyl tert-butyl ether and 19.62 g (75 mmol) of 3-methacryloyloxypropyltrichlorosilane were added to the flask as in Example 1. The system was returned to room temperature (25°C). The reaction was carried out for 3 days (72 hours) under the stirring of a magnetic stirrer and the entire flask was required to be shaded with aluminum foil. Upon completion of the reaction, bismuth trichloride is removed by filtration through diatomaceous earth as it precipitates in the reaction solution. Finally, the yield of 3-(methacryloxy)propyltrimethoxysilane was determined. The experimental results were recorded in Table 2.

Questions And Answer

• Introduction

  3-Methacryloxypropyltrimethoxysilane is a methacryl-functional silane, it is a clear, light and heat sensitive liquid with a faintly sweet odour.
  3-Methacryloxypropyltrimethoxysilane is used as adhesion promoter at organic/inorgainc interfaces, as surface modifier (e.g. imparting water repellency, organophilic surface adjustment) or as crosslinking of polymers). It is used as a coupling agent to improve the physical and electrical properties of glass-reinforced and mineral-filled thermosetting resins under exposure to heat and/or moisture. It is typically employed as a blend additive in resin systems that cure via a free radical mechanism (e.g. polyester, acrylic) and in filled or reinforced thermoplastic polymers, including polyolefins and polyurethanes. It is also used to functionalize resins via radical initiated processes - copolymerization or grafting - and to modify surfaces.
  Applications:
  • 3-Methacryloxypropyltrimethoxysilane can improve strength as glass fiber size composite in reinforced polyester composites.
  • Enhance initial and wet strength of reinforced polyester resin composites.
  • Enhance the wet electrical properties of many mineral-filled and reinforced composites.
  • Crosslinked acrylic type resins can improve adhesion and durability of adhesives and coatings.
