  • Patent number: 6777475
    Abstract: A resin composition of the invention includes a thermoplastic elastomer and a glycol or its derivative. Polyamide- or polyester-based thermoplastic elastomers, for example, can be used as the thermoplastic elastomer. The soft segment of the thermoplastic elastomer may be composed of a polyether or polyester. As the glycol or its derivative, for example, a compound represented by the following Formula (1): R1O&Parenopenst;A1—O&Parenclosest;l&Parenopenst;A2—O&Parenclosest;m&Parenopenst;A3—O&Parenclosest;nR2  (1) (wherein each of R1 and R2 is, identical to or different from each other, a hydrogen atom, an alkyl group or an acyl group; each of A1, A2 and A3 is, identical to or different from one another, an alkylene group having 2 or more carbon atoms; each of l, m and n is, identical to or different from one another, an integer of 0 or more, where l+m+n>0) can be used.

  • Patent number: 6517949
    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.

  • Patent number: 5278237
    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.

  • Patent number: 5244984
    Abstract: A polymer powder is produced by separately melting two or more of oligomers and monomers which are reactive with each other, spraying a mixture of the oligomers and the monomers, while continuously mixing them with each other, the mixture being solid at a normal temperature, having a melt viscosity of 1,000 cps or below at 300 degree C., then cooling the sprayed mixture to obtain a powder thereof, and solid phase-polymerizing it to obtain the polymer powder. It is useful for powder coating.

  • Patent number: 5042848
    Abstract: A swivelable connector for tubular conduits comprising first and second mutually insertable tubular connector members and a retainer for retaining the second tubular connector member in the first tubular connector member. The retainer comprises engaging members positionable around the second tubular connector member and in the first tubular connector member, urging members engageable with the outer surfaces of the engaging members along a relatively axial movement between the urging members and the engaging members, to radially urge the engaging members into engagement with the second tubular connector member. The urging members can be embodied by a stepped inner surface of the first tubular connector member associating with the movable engaging members, or by the movable urging members associating with the fixed engaging members.
