Abstract
PURPOSE: To provide a title composition capable of forming a highly foamed article with a uniform fine cell structure obtained by compounding a vinyl chloride type resin impregnated with a foaming agent, a nucleating agent, a styrene type resin and a dispersible foaming agent.
CONSTITUTION: 100pts.wt. of a vinyl chloride type resin (a) obtained by impregnating 1wt% or more of an aliphatic (halogenated) hydrocarbon with b.p. of 90°C or less (pref. 70°C or less) such as propane, methyl chloride to a vinyl chloride type polymer with an average polymerization degree of 300W2,000, a void volume of 0.2ml/g or less and a vinyl acetate content of 0W40wt%, 0.01W20pts.wt. of a nucleating agent (calcium carbonate, bentonite or the like) (b) with a particle size of pref. about 30μ or less, 0.5W30pts.wt. of a styrene type resin (c) with reduced viscosity (chloroform solution, 25°C) of 3dl/g or more and 0W5pts.wt. of a decomposable foaming agent (e.g., azodicarbonamide) (c) generating a gas by decomposing at a temp. lower than the molding temp. of a vinyl chloride type polymer (component "a") are compounded.
