The Uses of 3-Methacryloxypropyltrimethoxysilane

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.
