Abstract: A process for producing a polydiorganosiloxane based graft copolymer is provided. The process involves producing an emulsion of crosslinked polydiorganosiloxane by admixing dihydroxyfunctional polydiorganosiloxane, an emulsifying agent, and water; polymerizing the polydiorganosiloxane in the presence of an acid catalyst, a cross linking agent and a grafting agent to form silicone rubber particles having functional sites, and graft polymerizing a vinyl functional monomer onto the resulting silicone particles. The process provides several advantages in a rubber particle size control thereby resulting in better control of the properties of the resulting graft copolymer.

Abstract: A thermoplastic composition is provided which exhibits the combined properties of high gloss, reduced viscosity, desirable levels of dart impact strength and reduced levels of opacity. The compositions contain respective amounts of a bulk vinyl aromatic-vinyl cyanide-rubber graft copolymer, an emulsion vinyl aromatic-vinyl cyanide-rubber graft copolymer, a high molecular weight vinyl aromatic-vinyl cyanide rigid copolymer, and a low molecular weight vinyl aromatic-vinyl cyanide rigid copolymer. The emulsion graft copolymer utilizes as the rubber a vinyl aromatic-diene rubber. The thermoplastic compositions are useful for making molded articles exhibiting high gloss and desired levels of dart impact strength and opacity.

Abstract: A process that is provided for agglomerating rubber particles of a rubbery latex. The process involves producing an agglomerating agent which is in the form of latex having particles which comprise high molecular weight polyoxyethylene bound therein. The agglomerating agent is affixed with an elastomeric latex to form agglomerated elastomeric particles. The process results in the formation of uniform size agglomerating particles, and utilizes a non-surfactant form of polyoxyethylene, which can be utilized in small amounts to yield the desired agglomerated elastomeric latex. The agglomerated particles may then be utilized as the substrate for graft copolymers, such as acrylonitrile-butadiene-styrene graft copolymers.

Abstract: Polymer blends are provided which exhibit reduced surface gloss while maintaining impact and flow properties. The blends comprise an aromatic polycarbonate resin, an acrylonitrile-butadiene-styrene graft copolymer and an ionomeric resin. The blends are useful as molding resins for making molded plastic parts exhibiting reduced surface gloss.
