PURPOSE:To homogeneously disperse a plasticizer highly compatible with a thermoplastic polyurethane in preparing the title compsn. contg. a vinyl chloride resin, the polyurethane, an ethylene-vinyl acetate copolymer, and the plasticizer as the main components by allowing the polyurethane to absorb the plasticizer in advance. CONSTITUTION:The title compsn. mainly comprising 70-130 pts.wt. vinyl chloride resin, 130-70 pts.wt. thermoplastic polyurethane, 5-50 pts.wt. ethylene-vinyl acetate copolymer, and 5-50 pts.wt. plasticizer highly compatible with the polyurethane is prepd. by allowing the polyurethane to absorb the plasticizer before mixing with other ingredients. |
