Abstract of the Disclosure There is provided a method of producing a foamable vinyl chloride resin composition for powder molding in which from 40 to 120 parts by weight of a plasticizer is blended with 100 parts by weight of a granular vinyl chloride resin obtained by suspension polymerization or bulk polymerization. From 0.5 to 40 parts by weight of at least one polymer or copolymer having an active hydrogen in the molecule and from 0.1 to 10 parts by weight of a crosslinkable isocyanate compound are added and dry- blended, and while the temperature of the dry-blend system is in the course of cooling after it has reached a maximum temperature, from 3 to 25 parts by weight of a finely powdered vinyl chloride resin obtained by emulsion poly- merization or micro-suspension polymerization is added to coat the dry-blend. The composition produced by this method contains no coarse agglomerate particles, has powder flowability suitable for powder molding, and has excellent foamability to produce a foam having flexibility and good shape recovery after compression.
