Abstract
PURPOSE:To obtain the captioned molded body having a homogeneous and fine cell structure and a constant density by a method wherein a composition comprising vinyl chloride resin containing a specific compound, a foam equalizing assistant and acryl resin, etc. is controlled in the range of specific temperature and distribution of temperatures is equalized. CONSTITUTION:After a composition composed of (A) (b) a vinyl chloride resin where 1% or more by weight of aliphatic (halogenated) hydrocarbon having boiling points 90 or less deg.C impregnated as a foaming agent to (A) (a) the vinyl chloride polymer (vinyl chloride-vinyl acetate copolymer being most suitable) when void volume is of 0.2 or less ml in one gram of polymer, (B) a foam equalizing assistant (examples; azodicarboxylic acid amide and the like) and (C) an acryl and/or a styrene resin for accelerating gellation is heated, melted and kneaded, the said composition is controlled in the range of the temperature which is 30 or more deg.C beyond the softening point of the said composition and 10 deg.C lower than the apparent gelling temperature and let to foam under the equal distribution of temperature.
