POLYVINYL CHLORIDE RESIN COMPOSITION AND EAVESTROUGH USING THE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a polyvinyl chloride resin composition and an eavestrough excellent in a low linear expansion, impact resistance and heat resistance using the resin composition. SOLUTION: The polyvinyl chloride resin composition contains 80-40 wt.% of (component a) a vinyl chloride-based graft copolymer consisting of a vinyl chloride monomer and grafted with a saturated elastic body and 20-60 wt.% of (component b) a polyvinyl chloride resin consisting solely of a vinyl chloride monomer or a post-chlorinated polyvinyl chloride resin and 20-50 pts.wt. of (component c) wollastonite. The eavestrough is composed of the resin composition. COPYRIGHT: (C)2008,JPO&INPIT
