Abstract: A polyacetal composite according to the invention includes a polymer unit (A) composed of a polyacetal resin, and a polymer unit (B) composed of a thermoplastic resin or elastomer having an acidic group, and the polymer unit (A) and the polymer unit (B) directly adhere to each other. The acidic group includes, for example, a carboxyl group and a carboxylic anhydride group. The thermoplastic resin or elastomer having an acidic group includes a comonomer having at least one selected from among acrylic acid, methacrylic acid, fumaric acid, maleic acid, maleic anhydride, and itaconic acid as a comonomer, and typical examples thereof include, for example, acid-modified polystyrene and acid-modified NBR (acid-modified nitrile rubber). In this polyacetal composite, the polyacetal resin and another polymeric material are firmly fixed with each other.

Abstract: Disclosed are a composition for use in sculpturing, which comprises a resin composition consisting essentially of a polyoctenamer resin and an inorganic filler, and a process for manufacturing a sculptured product comprising using a sculpturing material composition comprising a polyoctenamer resin.The composition for use in sculpturing can be not only molded at moderate temperature by hands and a trowel but also sculptured or shaved with a chisel or a boaster, and even polished with a rasp or a sandpaper.The composition can be made easier by mixing with an inorganic filler and said mixing provides excellent surface smoothness and massiveness effects in handling the sculptured products.

Abstract: Disclosed are a sculpturing resin composition which comprise comprising a polyoctenamer resin and a polyolefin copolymer and/or a modified polyolefin resin, and a process for sculpturing a sculptured product.The sculpturing composition has an excellent property of not shrinking even after elapse a long period of time, and is capable of being molded by hand at moderate temperatures, sculptured or shaved with a chisel, etc., and also being polished or ground with a rasp, etc., in comparison with conventional sculpturing materials.The anti-shrinking property of the polyoctenamer resin is found to be improved specifically by the mixing with a polyolefin copolymer and/or a modified polyolefin resin.

Abstract: A vibration damping sheet comprises two sheets of metal and an intermediate layer inserted between the two sheets of metal. The intermediate layer comprises a rubber composition comprising a butyl rubber, polyoctenylene and a copolymer of an olefin and an epoxy-containing acrylic ester.

Abstract: A polyamide resin composition is used in powder coating and comprises a first polyamide having a carboxylic acid at 70 percent or above of the terminal groups thereof and a second polyamide having an amine at 70 percent or above of the terminal groups thereof.
