Abstract:
A golf ball consisting of:a core having a diameter of between about 1.54 and about 1.58 inches and a compression of between about 22 and about 50, the core comprising: a polybutadiene rubber having a Mooney viscosity of less than about 50 and a halogenated organosulfur compound present in an amount of at least about 2.2 parts per hundred parts of polybutadiene rubber, the halogenated organosulfur compound having the formula: where R1-R5 are C1-C8 alkyl groups; halogen groups; thiol groups; carboxylated groups; sulfonated groups; or hydrogen and at least one of R1-R5 are halogen; and a filler comprising a trans-regrind polybutadiene rubber having a trans-isomer content of between about 10% and about 60% and present in an amount of from about 5 parts to about 26.5 parts per hundred parts of cis-1,4-polybutadiene rubber; and a cover having a thickness of between about 0.05 inches and about 0.1 inches, the cover consisting essentially of a first ionomeric material and a second ionomeric material; wherein the golf ball has a coefficient of restitution of at least about 0.813 when measured at 125 ft/s.
