Title:
VINYL CHLORIDE RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP3926343
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a molded product comprising a maleimide copolymer and a vinyl copolymer each having a specific composition in specific proportions, and having excellent heat resistance, impact resistance, processability and color.
SOLUTION: The vinyl chloride resin composition incorporates (A) 70-95 mass% of a vinyl chloride polymer whose average degree of polymerization is 700-1,700, (B) 1.5-15.0 mass% of a maleimide copolymer which consists of 15-70 mass% of an aromatic vinyl monomer, 25-65 mass% of an unsaturated dicarboxylic acid imide derivative, 0-25 mass% of an unsaturated dicarboxylic acid anhydride monomer and 0-40 mass% of a vinyl monomer copolymerizable with these and whose weight average mol. wt. is 60,000-140,000, and (C) 2.5-21.0 mass% of a vinyl copolymer which consists of 40-85 mass% of an aromatic vinyl monomer, 15-40 mass% of a vinyl cyanide monomer and 0-40 mass% of a vinyl monomer copolymerizable with these and whose weight average mol. wt. is 50,000-110,000.
