ABSTRACT:
A composition for making golf ball products is disclosed. Polybutadiene is crosslinked by zinc diacrylate with the use of a free radical initiator, such as a peroxide. The amount of free radical initiator used is between 0.2 parts and 0.8 parts per 100 parts polybutadiene. The amount of zinc diacrylate and free radical initiator are controlled and the curing conditions adjusted so that the golf ball product has a swell index of at least about 0.6 and a PGA compression of about 50-110.
