SURFACE PHYSICAL PROPERTY MODIFIER COMPOSITION FOR POLYOLEFINE RESIN MOLDING, AND RESIN COMPOSITION CONTAINING THE SAME AND ITS RESIN MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a surface physical property modifier composition for a polyolefine resin molding that can keep excellent scratch resistance even when the resin molding is exposed in severe environment.;SOLUTION: The surface modifier composition includes 50 to 90 pts.mass of a non polar wax (A) having a melting point of 50 to 100°C, and 10 to 50 pts.mass of a vinyl copolymer (B) that is formed by radical copolymerization of two monomers (b1) and (b2), wherein (A)+(B)=100 by pts. weight. The monomer (b1) is styrene and/or acrylonitrile. The monomer (b2) is methacryloxy polyorganosiloxane as shown by general formula (1), wherein m in the formula is an integer. The vinyl copolymer (B) includes 0.1 to 49.9 pts.mass of the monomer (b1), and 0.1 to 9.9 pts.mass of the monomer (b2) in the range of (b1)+(b2)=10 to 50 pts.mass. The surface physical property modifier composition of 0.5 to 10 pts.mass is added to 100 pts.mass of the polyolefin resin.;COPYRIGHT: (C)2013,JPO&INPIT
