Claim Text:
1. A method for preparing a golf ball composition comprising: a step of producing a diene polymer (A) having a smallest molecular weight value of at least 3,000; which is synthesized using as a catalyst at least one type of complex selected from the group consisting of metallocene complexes of general formulae (I) and (II) below, and half-metallocene cation complexes of general formula (III) below, and using an organolaluminum compound of the general formula AIRR′R″ wherein R and R′ are each independently a C wherein in formula (I), each occurrence of Cp R wherein in formula (II), each occurrence of Cp X′ is a hydrogen atom, a halogen atom, an alkoxide group, a thiolate group, an amide group, a silyl group or a hydrocarbon group having 1 to 20 carbons; L is a neutral Lewis base; and w is an integer from 0 to 3; wherein in formula (III), Cp a step of compounding the diene polymer (A) with an unsaturated carboxylic acid and/or a metal salt thereof (B), and an organic peroxide (D) to make up the golf ball composition.
