Abstract

A golf ball comprising a core and at least one layer disposed about the core, wherein at least one of the core and the layer comprises a thermoplastic or thermoset composition comprising a reaction product of a polyurethane or polyurea prepolymer comprising at least one isocyanate and a curative comprising a blend of at least one aliphatic diamine and at least one polyaspartic ester formed from reactants comprising at least one aliphatic primary polyamine and at least one maleic or fumaric diester, and wherein the thermoplastic or thermoset composition comprises a gel time of about 90 seconds or greater. Also, a golf ball comprising a core and at least one layer disposed about the core wherein at least one of the core and the layer comprises a thermoplastic or thermoset composition T comprising a reaction product of a polyurethane or polyurea prepolymer P comprising at least one isocyanate and a curative C comprising a blend of at least one aliphatic diamine D and at least one polyaspartic ester formed from reactants comprising at least one aliphatic primary polyamine and at least one maleic or fumaric diester, wherein the thermoplastic or thermoset composition T has a gel time X such that X>1.25Y, and wherein Y is the gel time of a thermoplastic or thermoset composition T′ comprising a reaction product of the polyurethane or polyurea prepolymer P and a curative C′ comprising a blend of aliphatic diamine D and a polyaspartic ester consisting of N,N′-diethylmaleate-2-methyl-pentamethylene diamine.
