Heat resistant copolymer composition.

摘要

A heat resistant copolymer composition is provided by blending two kinds of copolymers one of which is obtainable by polymerizing a maleimide monomer (A), an aromatic vinyl monomer (B), and unsaturated nitrile monomer (C) and optionally at least one other comonomer copolymerizable therewith (D) in a specific monomer ratio in the presence or absence of an elastomeric polymer and which has an intrinsic viscosity of 0.3 to 1.2 dl/g, and another of which is obtainable by copolymerizing the aromatic vinyl monomer (B), the unsaturated nitrile (C) and optionally at least one other comonomer copolymerizable therewith (D) in a specific monomer ratio in the presence or absence of the elastomeric polymer and which has an intrinsic viscosity of 0.3 to 1.5 dl/g.
