  • Polyurethane rubbers vulcanizable by peroxides or sulphur with improved low temperature and low gas impermeability properties
    Patent number: 5760158
    Abstract: Polyurethane rubbers are disclosed vulcanizable by peroxide and/or sulphur, the vulcanized rubber having improved low temperature compression set properties and low gas permeability. The vulcanizable polyurethane rubbers are made by mixing(A) 1.0 mol of polyester glycol having a molecular weight of 1500 to 7000 consisting of adipic acid and 2-methylpropanediol-1,3 in combination with cyclohexyldimethanol and/or propanediol. The mol ratio of methylpropanediol to cyclohexyldimethanol and/or propanediol can vary from 70 to 30 to 30 to 70%.(B) 0 to 2.5 mols of a diol having a molecular wright of 60 to 200; and(C) 0.95 to 3.5 mols of diisocyanate with a molar ratio of isocyanate group in (C) to the isocyanate-reactive groups in (A) and (B) of 0.95 to 1.02.
