Abstract:
1. A thermoplastic composition comprising the melt blending product of: from 10 to 75 percent by weight of a continuous phase, based on the total weight of the thermoplastic composition, wherein said continuous phase comprises one or more thermoplastic polymers; and from 50 to 80 percent by weight of a dispersed phase comprising one or more core/shell polymer particles, based on the total weight of the thermoplastic composition, wherein said one or more core/shell polymer particles comprise a crosslinked elastomer core and a thermoplastic shell and wherein said core/shell polymer has an average particle size diameter in the range of from 70 to 10,000 nm; wherein said crosslinked elastomer core comprises an elastomeric crosslinked component having a glass transition temperature in the range of from less than 0° C.; wherein said crosslinked elastomer core comprises crosslinked polydimethylsiloxane copolymers; and wherein said crosslinked polydimethylsiloxane copolymers comprise one or more monomers selected from the group consisting of vinylmethyldimethoxysilane, allylmethyldimethoxysilane, mercaptopropylmethyldimethoxysilane, butadiene, styrene, butyl acrylate, ethyl acrylate, 2-ethyl hexyl acrylate, propyl acrylate, methyl acrylate, hexyl acrylate, butylmethacrylate, ethylhexyl methacrylate, benzyl acrylate, and crosslinking monomers selected from the group consisting of divinylbenzene, trimethylolpropane triacrylate, ethylene glycol dimethacrylate, trimethylolpropane trimethacrylate, allyl methacrylate, blends thereof, and combinations thereof.
