PROBLEM TO BE SOLVED: To provide a vinyl chloride resin composition having a high heat-melt- molding processability and a molded product thereof. SOLUTION: A vinyl chloride resin composition contains (A) 50 to 99.9 wt.%, vinyl chloride resin, (B) 50 to 0.1 wt.% copolymer which comprises an aromatic vinyl compound, a vinyl cyanide compound and, if required, other vinyl monomers copolymerizable with these compounds and has an intrinsic viscosity of 1.5 dl/g or larger and a ratio of the weight average molecular weight to the number average molecular weight of larger than 3.0 and (C) from 0 to 49.9 wt.% of another thermoplastic polymer [(A)+(B)+(C)=100 wt.%] as main components. A molded product is prepared through (expansion) extrusion molding, blow molding, injection molding, calendaring, vacuum or pressure forming or inflation molding of the vinyl chloride resin composition. |
