  • Polyurethane elastomer produced by reaction between a triazole-stabilized isocyanate prepolymer and a diamine
    Patent number: 4096128
    Abstract: A method for producing a urethane elastomer is disclosed. The method involves mixing benzotriazole or a tolyl triazole with an isocyanate terminated prepolymer while the prepolymer is at a temperature sufficiently high that it is a liquid. The proportion of benzotriazole or tolyl triazole used can range from 0.1 to 1.0 equivalent per equivalent of isocyanate in the prepolymer, and must be sufficient to increase the pot life of a mixture of the prepolymer with a diamine, but insufficient to cause substantial impairment of the physical properties of the cured elastomer. A substantially equivalent amount of a diamine is then mixed with the stabilized prepolymer, and the resulting composition is heated to produce the elastomer.
