Abstract
A heat resistant thermoplastic resin composition comprising (a) 5 to 99% by weight of a poly(phenylene ether), (b) 95 to 1% by weight of a thermoplastic resin which is obtained by polymerizing in the absence of a rubber-like polymer a resin constituent mixture comprising an aromatic alkenyl compound, an alkenyl cyanide compound, and, if necessary, other alkenyl monomers copolymerizable with said monomers, and (c) up to 94% by weight of other styrenic resins, said thermoplastic resin (b) comprising (A) 1-50% by weight of a polymer having an alkenyl cyanide compound content of 1% by weight or more but less than 10% by weight, (B) 1-70% by weight of a polymer having an alkenyl cyanide compound content of 10% by weight or more but less than 20% by weight, (C) 5-90% by weight of a polymer having an alkenyl cyanide compound content of 20% by weight or more but less than 40% by weight, and (D) up to 70% by weight of a polymer having an alkenyl cyanide compound content of 40% by weight or more, and having a total alkenyl cyanide compound content of 10 to 40% by weight and an intrinsic viscosity of preferably 0.1- 1.5 dl/g as measured in methyl ethyl ketone at 30.degree. C. The above thermo…
