Abstract

A polymethacrylimide resin composition having an improved impact resistance and thermal resistance is prepared by blending a polymethacrylimide resin with a polyorganosiloxane type graft copolymer formed by graft-polymerizing at least one ethylenically unsaturated monomer onto a polyorganosiloxane rubber copolymerized with a graft-crosslinking agent.
