ABSTRACT:
In order to prevent a thermoplastic resin possessing an unsaturated nitrile unit from discoloration, the thermoplastic resin prepared by copolymerizing at least an unsaturated nitrile compound as a polymerizing component in the presence or absence of a rubbery polymer is blended with 2,4-di-t-amyl-6-[1-(3,5-di-t-amyl-2-hydroxyphenyl)ethyl]phenyl acrylate. The resulting composition shows little discoloration during the production and processing stages.
