Abstract:
A golf ball comprising:a core formed from a composition including (i) from about 80 parts to about 120 parts by weight of elastomer components, said elastomer components including a first polybutadiene, said first polybutadiene synthesized in the presence of a cobalt or nickel catalyst, which prior to curing exhibits a Mooney viscosity of from about 65 to about 85, and a second polybutadiene, said second polybutadiene synthesized in the presence of a neodymium or lanthanide series catalyst, and (ii) at least about 60 parts by weight of non-elastomer components, wherein said composition comprises said first polybutadiene in a proportion of less than 50 parts per 100 parts of said first polybutadiene and said second polybutadiene; and at least one or more cover layers disposed about said core.
