  • Patent number: 8791224
    Abstract: Compositions for golf balls that are formed from the reaction product of an isocyanate-containing component and an amine-terminated component having an unsaturated backbone, which is cured with a curing agent. In particular, the compositions of the invention may be formed from a prepolymer having urea linkages and at least one carbon-carbon double bond in the backbone that is cured with an amine-terminated component resulting in golf balls having weight gain comparable to ionomers and less loss of COR as compared to ionomers and conventional polyurethanes after submersion in water.
