Abstract: A vinyl chloride resin composition having far improved compression set and heat deformation resistance and further having a superior tensile strength, wear resistance and processability is provided. The composition includes 1 to 100 parts by weight of a polyol compound and 1 to 100 parts by weight of a crosslinking agent (e.g., a polyisocyanate compound) blended with 100 parts by weight in total of 1 to 100 parts by weight of a crosslinkable vinyl chloride resin and 99 to 0 parts by weight of a vinyl chloride resin, wherein the crosslinkable vinyl chloride resin is a copolymer or vinyl chloride monomer with an active hydrogen atom-containing unsaturated monomer. The composition may further comprise a plasticizer and/or a rubbery material.

Abstract: A resin for powder molding having a superior flow-ability; capable of faithfully duplicating the patterns of a mold even when the mold has a complicated structure and fine projection and depression parts; capable of obtaining a molded product having a uniform thickness and no pinholes; and having a good storage stability over a long term, and a process for producing the resin are provided, which resin is obtained by coating a powdery vinyl chloride resin composition containing plasticizer with a high polymer film component on the surface of the composition.

Abstract: A process which produces a vinyl chloride resin composition for powder molding by mixing a vinyl chloride resin, a plasticizer and at least one vinyl chloride resin modifying additive in a mixer is provided, which process includes the following steps (A), (B), and (C): (A) feeding a powdery vinyl chloride resin, a plasticizer and at least one vinyl chloride resin modifying additive to a high-speed agitating mixer provided with agitating elements, a jacket, a gas-inlet port and a gas-outlet port and mixing these materials with stirring while heating them to 120.degree. C. to 130.degree. C.; (B) cooling the resulting materials in a mixer down to 70.degree. C. or lower; and (C) further adding thereto a vinyl chloride emulsion polymer and mixing the resulting materials with stirring at 70.degree. C. or lower.

Abstract: A process for producing a molded article is provided includinga) The surface of a mold is cooled with a releasing agent for powder molding which has, as an essential component, a copolymer AB derived from at least one monomer A represented by the following general formula (I) ##STR1## wherein X is a hydrogen atom or a methyl group, k is an integer of 0-5, l is an integer of 1-3, m is an integer of 1-3, n is an integer of 0-550 and Y is a methyl group or a fluorine atom-containing substituent having 1-20 carbon atoms,and at least one vinyl-polymerizable monomer B containing at least one alkyl acrylate or alkylmethacrylate wherein the alkyl group has 1 to 8 carbon atoms.b) The coated mold is heated.c) A powder of a non-rigid vinyl chloride resin containing a plasticizer is allowed to adhere to the heated mold to melt the powder.d) The mold, releasing agent and powder are cooled to form a molded article.e) The molded article is peeled from the mold.
