ABSTRACT:
A golf ball is manufactured by molding and vulcanizing a rubber composition comprising 100 pbw of a base rubber composed primarily of a polybutadiene having a cis-1,4 content of at least 60 wt % and a Mooney viscosity of at least 30 and synthesized using a rare-earth catalyst, 15–50 pbw of an unsaturated carboxylic acid and/or a metal salt thereof, at least 2 pbw of a processing aid having a highest melting point of up to 115° C., and 1–5 pbw of an organic peroxide. The golf ball can be efficiently manufactured and has excellent rebound characteristics.
