摘要： A monomer mixture comprising .alpha.-methylstyrene or 2-isopropenylnaphthalene, methyl methacrylate, and acrylonitrile is polymerized in the presence of a crosslinked polymer obtained by copolymerizing a monofunctional monomer such as .alpha.-methylstyrene with a small quantity of a polyfunctional monomer such as divinylbenzene to obtain a copolymer (C). A vinyl chloride resin composition formulated by blending the copolymer (C) thus obtained with a vinyl chloride resin and an impact strength modifier resin in a specific proportion possesses improved thermal deformation resistance and impact strength while retaining processability comparable to that of the vinyl chloride resin mixed with the impact strength modifier resin.

摘要： A resinous composition having fire retardance, impact resistance and easy workability is obtained by blending (1) about 80 to 30 parts by weight of an ABS resin with (2) about 20 to 70 parts by weight of (i) a vinyl chloride resin compound comprising 100 to 5 parts by weight of a copolymer resin consisting essentially of 0.5 to 40% by weight of a higher alkyl vinyl ether and 99.5 to 60% by weight of vinyl chloride and (ii) 0 to 95 parts by weight of a polyvinyl chloride resin.
