Claim:
A method for improving the feel and rebound velocity of a golf ball, the method comprising: preparing a golf ball from a rubber composition that comprises: a rubber, from about 3 to about 12 parts by weight of a processing additive per 100 parts by weight rubber, where said processing additive includes: i) a high-HLB surfactant having a hydrophilic-lipophilic balance of 3 to 35, where the high-HLB surfactant is (a) a fatty acid ester of C 5 or C 6 sugars or (b) polyoxyethylene derivatives of fatty acid esters of C 5 or C 6 sugars, or ii) at least two distinct zinc fatty acid salts, where the at least two distinct fatty acids salts include at least one saturated fatty acid salt and at least one unsaturated fatty acid salt, from about 18 to about 32 parts by weight of a multi-functional crosslinking agent per 100 parts by weight rubber, from about 0.2 to about 1.0 parts by weight of a cure initiator per 100 parts by weight rubber, from about 0 to about 25 parts by weight zinc oxide per 100 parts by weight rubber, and from about 0 to about 0.7 parts by weight antioxidant.
