摘要：A process for producing an impact resistant graft polymer which comprises firstpolymerizing a portion of monomer mixture (b) consisting of specified unsaturated acid,alkyl acrylate having C-C alkyl and other copolymerizable monomer (said portion ofmonomer mixture (b) does not contain said unsaturated acid), followed by consecutivelypolymerizing the residual portion of monomer mixture (b) (said residual portion ofmonomer mixture (b) contains said unsaturated acid) to obtain an acid residue-containingcopolymer (B) latex, adding 0.1-5 parts by weight (as weight of solid component) of saidacid residue-containing copolymer (B) latex to 100 parts by weight (as weight of solidcomponent) of synthetic rubber (A) latex which has been adjusted to pH 7 or higher toobtain an agglomerated rubber (C) latex, and polymerizing 93-30 parts by weight of agrafting monomer (d) comprising 30% by weight or more of at least one monomerselected from styrene, acrylonitrile and methyl methacrylate in the presence of 7-70parts by weight (as weight of solid component) of said agglomerated rubber (C) latex.
