PURPOSE:To obtain a crosslinked foamed sheet excellent in shape retention after molding by adding a specified modifier to a vinyl chloride resin composition in a specified mixing ratio. CONSTITUTION:To a vinyl chloride resin (e.g. ethylene/vinyl chloride copolymer) composition is added at least 5 pts.wt., per 100 pts.wt. vinyl chloride resin, a modifier having a heat distortion temperature of 70 deg.C or above under specified conditions of ASTM standards (e.g. acrylonitrile/ styrene copolymer). |
