  • Polyurethane compositions and process for preparing polyurethane emitting reduced amounts of toxic fumes on burning using a cobalt, copper, nickel or manganese salt
    Patent number: 4263411
    Abstract: A process of forming polyurethane compositions which emit reduced amounts of toxic smoke on burning is described. The process comprises reacting a mixture of an organic compound having two or more active hydrogen atoms, an organic polyfunctional isocyanate, a catalyst and at least one metal salt of an aliphatic or alicyclic monocarboxylic acid wherein the metal is cobalt, copper, nickel or manganese. The metal salt is added to the mixture in an amount which is sufficient to reduce the formation of toxic substances when the polyurethane is ignited.

  • Elastomers with improved metal adhesion
    Patent number: 4154911
    Abstract: Vulcanizable elastomeric compositions are described which comprise an elastomer and from about 0.001 to about 0.1 lb mole of metal per 100 lbs of elastomer, the metal content comprising a mixture of copper and zinc, said metals being present as(a) an organic carboxylic acid salt consisting of copper and zinc combined with one or more carboxylic acids,(b) a combination of two or more copper and zinc salts of organic carboxylic acids, or(c) a combination of a metal salt of an organic carboxylic acid and a mixed organic acid salt complex.Such vulcanizable elastomeric compositions exhibit improved adhesion to brass plated metal surfaces and are, therefore, useful in preparing rubber laminates containing metal reinforcing elements.

  • Elastomers with improved metal adhesion
    Patent number: 4137359
    Abstract: Vulcanizable elastomeric compositions are described which comprise an elastomer and from about 0.001 to about 0.1 lb mole of metal per 100 lbs of elastomer, the metal content comprising at least one metal which is an oxidizing constituent and a second metal which is a polymerizing constituent or calcium, said metals being present as(a) an organic carboxylic acid salt of two different metals combined with one or more carboxylic acids,(b) a combination of two or more different metal salts of organic carboxylic acids, or(c) a combination of a metal salt of an organic carboxylic acid and a mixed organic acid salt complex.Such vulcanizable elastomeric compositions exhibit improved adhesion to metal surfaces and are, therefore, useful in preparing rubber laminates containing metal reinforcing elements.
