ABSTRACT:
A filler-containing polypropylene resin composition is disclosed, comprising (a) from 30 to 90% by weight of a polypropylene resin, (b) from 2.5 to 38% by weight of an ethylene copolymer composed of from 82 to 98.7 mol % of ethylene, from 1 to 15 mol % of an ester selected from alkyl acrylate and alkyl methacrylates having from 1 to 8 carbon atoms in the alkyl moiety thereof and from 0.3 to 3 mol % of an unsaturated dicarboxylic acid anhydride, and (c) from 5 to 50% by weight of a filler. Molded products obtained from the composition have improved finishing properties, such as adhesion, coating properties, printability, and the like.
