  • Poly(urethane-urea) microcellular elastomer compositions
    Patent number: 5382646
    Abstract: Poly(urethane-urea) reaction injection molded compositions having improved processing and lower water absorption are prepared by reacting an isocyanate-terminated prepolymer prepared by reacting 4,4'-MDI or modified 4,4'-MDI and a polyoxypropylene glycol having a molecular weight of from 400 to 2500 with a polyether polyol and a hindered amine or glycol chain extender, in the presence of a urethane-reaction promoting catalyst, optionally including a hydroxyl terminated chain extender and internal mold release agent.
    Type: Grant
    Filed: August 2, 1994
    Date of Patent: January 17, 1995

  • Preparation of storage-stable, moisture-cured, single-component polyurethane systems and their uses
    Patent number: 4853454
    Abstract: A storage-stable, moisture-cured, single-component polyurethane system comprising(a) a polyurethane prepolymer having an NCO content of from about 1 to 10 weight percent prepared by the reaction of higher molecular polyols and aromatic polyisocyanates,(b) at least one polyaldimine having the structural formula ##STR1## in which R is a multivalent linear or branched or cyclic hydrocarbon radical, which optionally is interrupted by alkylene-, sulfonyl-, thio- and/or oxy groups as bridge members, or is a multivalent polyoxyalkylene radical,(c) optionally an aromatic and/or aliphatic carboxylic acid or arylsulfonic acid, and(d) optionally auxiliaries and/or additives.The polyurethane systems are useful as sealing, casting, patching, cementing and coating compounds.
