Polyurea composition suitable for a golf ball cover
First Claim
1. A polyurea composition suitable for molding golf ball covers comprising the reaction product of an organic compound having at least two isocyanate functional groups and an amine curing agent selected from the group of polymethylene-di-p-aminobenzoates, polydimethylsiloxane-bis(4-aminobenzoate), polytetramethyleneetherglycol-di-p-aminobenzoate, and polypropylene-glycol-di-p-aminobenzoate, wherein the equivalent weight ratio of amine functional groups to isocyanate functional groups is about 2.97.
