VINYL CHLORIDE-BASED RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a vinyl chloride-based resin composition excellent in processability and having a great value of fracture toughness. SOLUTION: This composition is obtained by compounding (A) 99-80 pts.wt. of a vinyl chloride-based resin with (B) 1-20 pts.wt. of a vinyl chloride-vinyl acetate copolymer. The average degree of polymerization of the vinyl chloride- vinyl acetate copolymer (B) is preferably 600-1,000 and the content of the vinyl acetate is preferably 4-15%. The average degree of polymerization of the vinyl chloride-based resin (A) is preferably 700-1,500.
