Abstract

PURPOSE: To obtain a highly expanded molding having a fine and uniform cellular structure, good compressive strength, and good dimensional stability, by adding a nitrile compound to a mixture of vinyl chloride, an organic solvent, and a foaming agent and then expanding the mixture.
CONSTITUTION: One hundred pts.wt. vinyl chloride resin (A), which may contain an inorganic filler in an amount approx. 1W9 times the weight of the vinyl chloride resin, approx. 30W80pts.wt. organic solvent (B), e.g., aromatic hydrocarbons of a boiling point of approx. 70W150°C, approx. 2W20pts.wt. foaming agent (C), e.g., N,N'-dinitrosopentamethylenetetramine, and approx. 10pts.wt. or less nitrile compound (D), e.g., acrylonitrile, nitrile rubber, etc., are mixed together. Then, the mixture is enclosed in a mold, heated uniformly to a temperature at which the foaming agent decomposes or vaporizes and also the vinyl chloride resin gells, and then cooled quickly while the mold is enclosed. Then, the mold is graudally depressurized and opened to obtain an expanded molding of an expansion ratio of approx. 2W5.
