Abstract
Golf balls are provided having a thermoplastic polyesterurethane cover comprising the reaction product of a polyester having a molecular weight from about 800 to 1500 reacted with para-phenylene diisocyanate or 1,4-cyclohexane diisocyanate, which is thereafter molded around a golf ball core.
Claims5
A golf ball comprising a core and a polyesterurethane cover comprising the reaction product of a polyester of an aliphatic diol containing 2 to 8 carbon atoms and an aliphatic dicarboxylic acid containing 4 to 8 carbon atoms, said polyester having a molecular weight of about 800 to about 1500, reacted with para-phenylene diisocyanate or 1,4-cyclohexane diisocyanate in a molar ratio of 0.98 1.01 mols of diisocyanate per mol of polyester, said polyester-urethane having a melt index in the range of about 15 to 50.
