<p>PURPOSE:To provide the titled resin compsn. which has excellent processability and gives non-rigid moldings having low compression set, by blending a plasticizer and fine inorg. filler with a vinyl chloride resin contg. emulsion-polymerized vinyl chloride polymer having a crosslinkage. CONSTITUTION:Vinyl chloride monomer is emulsion-polymerized in the presence of a polyfunctional compd. such as diallyl phthalate or a low-molecular diene polymer such as 1,4-trans-butadiene homopolymer as a crosslinking agent to prepare an emulsion-polymerized vinyl chloride polymer having a crosslinkage in the molecule. At least 30pts.wt. plasticizer such as diallyl phthalate and 0- 200pts.wt. inorg. filler having an average particle size of 1mum or below, such as calcium carbonate or talc, are blended with 100pts.wt. vinyl chloride resin contg. at least 1wt% of above polymer to obtain the desired vinyl chloride resin compsn.</p> |
