  • Elastomer and process for production thereof
    Patent number: 5334670
    Abstract: An elastomer is molded by a reaction injection molding of polyurethane resins, polyurea resins, polyurethane/urea resins and polyurea/amide resins in the presence of an internal release agent which is a polyester condensate of a saturated or unsaturated fatty acid having a hydroxy group produced by transesterification or a molecular end-aminated or iminated polyester condensate. The elastomer has a good releasing property and a good coating property.
    Type: Grant
    Filed: December 15, 1993
    Date of Patent: August 2, 1994
    Assignee: Mitsui Toatsu Chemicals, Inc.
    Inventors: Yuji Uchida, Yoshio Yoshida, Toshikazu Kaneda, Toshiaki Moriya, Tsutomu Kumazawa

  • Resin compositions and molded articles
    Patent number: 5198508
    Abstract: There is disclosed a resin composition comprising a product produced by the reaction of (a) a prepolymer prepared by reacting a diisocyanate with a hydroxy fatty acid ester or a mixture of a hydroxy fatty acid ester and a polyether polyol, with (b) at least one member selected from the group consisting of aromatic polyamines, polyether polyamines and polyether polyimines or a mixture of such a member as above and a polyether polyol. The resin composition is useful as an internal release agent for resins for reaction injection molding.
