Resin composition for improving impact resistance

TLDR: In this paper, the authors proposed a copolymer prepared by grafting a vinyl compound onto a rubber-like material and a graft or block copolymers obtained from a rubberlike polymer and a norbornene derivative.

Abstract: PURPOSE: The title composition having improved impact resistance, comprising a copolymer prepared by grafting a vinyl compound onto a rubber-like material and a graft or block copolymer obtained from a rubber-like polymer and a norbornene derivative. CONSTITUTION: A rubber-like material (A) or a copolymer (B) obtained by grafting 70W15 parts by wt. of a vinyl compound, e.g. a vinyl cyanide, aromatic vinyl or methacrylate compound, onto the material (A) or both are incorporated with a graft or block copolymer (C) obtained by bringing a mixture of a norbornene derivative having a polar group, e.g. a nitrile, ester, or N-substituted imido group, and a rubber-like polymer (D) having corbon-carbon double bonds into contact with a metathesis catalyst to give the total content of the material (A) and the polymer (D) in the composition of 30W85 wt.%.
