VINYL CHLORIDE RESIN COMPOSITION

PURPOSE:To prevent the lowering of mechanical properties, oil resistance and moldability caused by the addition of a large amount of filler, by compounding a vinyl chloride polymer uniformly with a specific crosslinked ethylene-vinyl acetate-vinyl chloride terpolymer. CONSTITUTION:The objective composition is prepared by compounding (A) 100pts.wt. of a vinyl chloride polymer uniformly with (B) >=20pts.wt. of a crosslinked ethylene-vinyl acetate-vinyl chloride terpolymer having a gel fraction of 5-50% and obtained by the graft polymerization of (i) 20-170pts.wt. of vinyl chloride to (ii) 100pts.wt. of an ethylene-vinyl acetate bipolymer containing 30-70wt% of vinyl acetate unit. When the terpolymer is crosslinked to attain a gel fraction of 10-30%, the improving effects to the mechanical properties and the oil resistance become particularly remarkable.
