ACRYL-MODIFIED NON-CHLORINATED POLYPROPYLENE-BASED RESIN COMPOSITION WITH EXCELLENT ADHESIVE FORCE, A PAINT COATING PREPARED BY THE COMPOSITION AND A PRODUCT PREPARED BY THE RESIN COMPOSITION

摘要

PURPOSE: An acryl-modified non-chlorinated polypropylene-based resin composition is provided to improve compatibility, paint dispersibility, pigment stability and scratch resistance by grafting acryl to a polypropylene resin which does not contain chlorine.;CONSTITUTION: An acryl-modified non-chlorinated polypropylene-based resin composition includes (A) 60-90 weight% of modified non-chlorinated polypropylene-based resin and (B) 10-40 weight% of acrylic resin. The modified non-chlorinated polypropylene-based resin(A) comprises (A-1) 35~65 weight% of high molecular weight polypropylene-based resin with average molecular weight of 100,000-300,000, (A-2) 30~60 weight% of low molecular weight polypropylene-based resin with average molecular weight of 10,000-50,000, and (A-3) 0.1~5.0 weight% of highly crystalline low molecular weight polypropylene-based resin with average molecular weight of 5,000-50,000.;COPYRIGHT KIPO 2011
