Abstract

PURPOSE: The titled composition having easy sizing process and high expansion ratio, capable of providing a molded article with high hardness, comprising a vinyl choride resin and a resin impregnated with a blowing agent obtained by impregnating a resin with an aliphatic (halogenated) hydrocarbon.
CONSTITUTION: (A) 100pts.wt. vinyl chloride resin is fed to a blender such as Henschel mixer, etc., dispersed while being heated, and cooled. This vinyl chloride resin is blended with (B) 5W100pts.wt. resin impregnated with a blowing agent obtained by blending a vinyl chloride type resin, preferably a copolymer of vinyl chloride and vinyl acetate, having a void volume per g of ≤0.2ml and an average degree of polymerization of preferably 300W2,000 with ≥5wt% preferably 7W30wt% aliphatic (halogenated)hydrocarbon (e.g., propane, etc.) having a boiling point of ≤90°C and impregnating the polymer with the hydrocarbon at ≤40°C.
