PROBLEM TO BE SOLVED: To provide a hard vinyl chloride-based resin composition capable of obtaining a molded article which is excellent in both of extrusion molding workability and injection molding workability, has no poor appearance such as fish eyes, and has beautiful appearance.SOLUTION: A vinyl chloride-based resin composition contains (a) 100 pts.mass of a vinyl chloride-based resin satisfying the following (1) and (2); and (b) 15 or less pts.mass of a plasticizer: (1) mass average molecular weight in terms of polystyrene of a differential molecular weight distribution curve measured by gel permeation chromatography of 98,500 or more and 110,000 or less; (2) molecular weight distribution Mw/Mn of 1.80-1.95, where Mw is mass average molecular weight in terms of polystyrene of differential molecular weight distribution curve measured by gel permeation chromatography, and Mn is number average molecular weight in terms of polystyrene.SELECTED DRAWING: None |
