Abstract
An improved thermoplastic resin composition obtained by subjecting a mixture of at least an engineering plastic and a rubber material containing an .alpha.,.beta.-unsaturated carboxylic acids or their derivatives, to dynamic heat treatment in the presence of a carbon radical inducing agent. The thermoplastic resin composition of the invention excels in thermal resistance, rigidity, impact resistance, and moldability.
