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 0W 200pts.wt. inorg. filler having an average particle size of 1μm 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.
