摘要：Disclosed is an impact-resistant thermoplastic resin composition comprising (a)a graft copolymer (II) prepared by polymerizing a monomer or monomer mixturepredominantly comprised of methyl methacrylate and/or styrene in the presence of anagglomerated rubber copolymer (I′) latex, and (b) bent-resistant rigid thermoplasticresin (III) comprised of α-methylstyrene or a maleimide compound. The agglomeratedrubber copolymer (I′) is prepared by emulsion-polymerizing an alkyl acrylate/1,3-butadiene mixture, and then agglomerating the resulting rubbery copolymer. Theagglomeration is effected by adding (a) an acid group-containing copolymer prepared byemulsion polymerizing an alkyl methacrylate/unsaturated monomer mixture, and/or (b)an oxy acid salt selected from alkali metal, alkaline earth metal, zinc, nickel and aluminumsalts of oxy acids having as the center element an element selected from elementsbelonging to the second and third periods of groups IIIA through VIA of the PeriodicTable.
