Thermoplastic resin composition

Abstract

Abstract PURPOSE: A composition that is made by adding a copolymer of an aromatic vinyl compound and a vinyl cyanide to a composition composed of an ethylene-propylene graft polymer and a propylene resin, thus having high dimensional stability, good coating properties and good processability. CONSTITUTION: To (A) 100pts.wt. of a composition composed of 5W95wt% of a graft polymer that is made by polymerizing 95W30wt% of more than 2 groups of compounds selected from aromatic vinyl compounds, preferably styrene, vinyl cyanides such as acrylonitrile and other polymerizable monomers, preferably methyl methacrylate in the presence of 5W70wt% of an ethylene-propylene rubber polymer and of 95W5wt% of a propylene resin, are added (B) 5W300pts. of a copolymer of 0.4W0.9 intrinsic viscosity, which is obtained by polymerizing 2 or more groups selected from aromatic vinyl compounds, vinyl cyanides and other polymerizable monomers and they are kneaded.
