The present invention a vinyl chloride resin composition having excellent mechanical properties. The vinyl chloride resin composition comprises a chlorinated polyolefin and a resin composition containing a vinyl chloride resin and a polyolefin resin, in which 1 to 30 parts by weight of the chlorinated polyolefin is included relative to 100 parts by weight of the resin composition including 50 to 99 parts by weight of the vinyl chloride resin containing 0 to 50 % by weight of a plasticizer and 1 to 50 parts by weight of the polyolefin resin, and in which the chlorinated polyolefin has a heat of fusion of 10 to 100 J/g, which is measured in accordance with a DSC method, and includes 35 to 60 % by weight of chlorine in amorphous portions thereof.
Abstract:
A flexible flame-retardant chlorinated polyolefin resin composition contains no plasticizer, generates almost no halogen-containing gas and no significant amounts of smoke during combustion. Uses thereof are also given. The chlorinated polyolefin resin composition comprises 50-95 parts of a chlorinated polyolefin, 50-5 parts of a copolymer of ethylene/a compound having ethylenic unsaturated groups/carbon monoxide (the total amount of this copolymer and the chlorinated polyolefin being 100 parts), 10-100 parts of a metal hydroxide, and 10-100 parts of calcium carbonate ("parts" herein indicates parts by weight); a formed article formed by shaping this chlorinated polyolefin resin composition; and a process for imparting flame retardancy using this chlorinated polyolefin resin composition.

Abstract:
The present invention relates to: a process for producing an organized clay which comprises: a step in which a lamellar clay mineral having a number-average particle diameter of 10-300 nm (layered silicate such as smectite, talc, kaolinite, or mica) is swollen with water or an aqueous solvent and hydroxy groups located on the edges of the swollen lamellar clay mineral are organized with a coupling agent, etc.; and a step in which an organic onium salt is then added to the lamellar clay mineral to conduct cation exchange in which metal cations present between the layers of the lamellar clay mineral are replaced with organic-onium ions in an amount corresponding to 60-120% of methylene blue (MB) adsorption equivalent; an organized clay which is obtained by the process and can be uniformly dispersed in a liquid resin while retaining substantially no layered structure; a resin composite (varnish, printing ink, coating material, etc.) comprising a liquid resin composition and the organized clay uniformly dispersed therein; and a cured object obtained from the resin composite.
Abstract:
The present invention relates to a method for producing an organized clay composite, wherein a step for cation exchanging an interlayer metal cation of a lamellar clay mineral to an organic onium ion by swelling the lamellar clay mineral with water or an aqueous solvent and then adding and mixing thereinto an emulsion which is obtained in advance by emulsifying a curable resin composition with use of an organic onium salt or with use of an organic onium salt and a nonionic surfactant, and a step for introducing the curable resin composition into the interlayer of the lamellar clay mineral are performed simultaneously. The present invention also relates to an organized clay composite obtained by the method. The present invention further relates to a resin molded product obtained by molding/curing such an organized clay composite. In the oreganized clay composite, the compound introduced into the interlayer of the lamellar clay mineral does not affect the physical properties of the matrix into which the organized clay is dispersed. Consequently, the organized clay composite has an expanded interlayer distance, while exhibiting good dispersibility.
