Resin composition for molding

Abstract

Abstract PURPOSE: The title composition having improved coating performance and printability without requiring surface treatment, comprising a styrene-butadiene copolymer, a styrene resin, an acrylic ester copolymer having specific functional groups, and polypropylene resin. CONSTITUTION: 100 parts by wt. of a polypropylene resin comprising 100 parts by wt. of a crystalline polypropylene resin and 3W20 parts by wt. of a modified polypropylene resin obtained by grafting at least one type of polar monomer, e.g. (meth) acnylic acid or their alkyl ester, is melt kneaded with (A) 3W20 parts by wt. of styrene-butadiene copolymer, (B) 5W50 parts by wt. of a styrene resin, and (C) 1W10 parts by wt. of an acrylic or methacrylic copolymer having or more types of functional groups, e.g. carboxyl, hydroxy, amido, and epoxy groups, and amino groups by means of a Banbury mixer.
