Polyorganosiloxane-containing graft copolymer, resin composition containing the same and method of manufacturing the polyorganosiloxane emulsion

摘要

Consisting of (C) copolymerizable monomer other polyfunctional monomers containing two or more polymerizable unsaturated bond in the molecule and (B) in the presence of a polyorganosiloxane latex (A) state polyorganosiloxane-containing graft copolymer by polymerizing (D) 0 - 10 parts by weight of vinyl monomer, E is by polymerizing the vinyl monomer (E) further. It is possible to be incorporated into the thermoplastic resin as a flame retardant, to obtain a resin composition having excellent impact resistance and flame retardancy. Method for producing a polyorganosiloxane emulsion of adding partial hydrolytic condensate thereof or condensation reaction of organosilane and polyorganosiloxane obtained by emulsion polymerization under the acidic conditions of pH5 following cyclic organosiloxane. It is possible to improve the polymerization conversion rate.
