PURPOSE: To provide a thermoforming non-rigid resin compsn. having excellent dimensional stability during molding, by blending a multi-component polymer rubber having a specified composition, an arom. vinyl compd. resin and a plasticizer for vinyl chloride resin with a vinyl chloride resin. n CONSTITUTION: 10W80pts.wt. multi-component copolymer rubber composed of a conjugated diene such as butadiene, an arom. vinyl compd. such as styrene or α-methylstyrene and a vinyl cyanide compd. such as acrylonitrile or these monomers and a polyfunctional vinyl compd. such as divinylbenzene, 0W100pts.wt. arom. vinyl compd. resin such as ABS resin or AS resin and 20W100pts.wt. plasticizer (e.g. diisodecylphthalate) for vinyl chloride resin, are blended with 100pts.wt. vinyl chloride resin. n COPYRIGHT: (C)1984,JPO&Japio |
