Patent ID: 7741407

Claim:
A golf ball having at least one layer formed from a composition comprising a multi-block copolymer, wherein the multi-block copolymer is produced by a process comprising: contacting ethylene under addition polymerization conditions with a catalyst composition, the catalyst composition comprising the admixture or reaction product resulting from combining: (A) a first olefin polymerization catalyst, (B) a second olefin polymerization catalyst capable of preparing polymers differing in chemical or physical properties from the polymer prepared by the first olefin polymerization catalyst under equivalent polymerization conditions, and (C) a chain shuttling agent, wherein at least one of the first olefin polymerization catalyst or the second olefin polymerization catalyst is capable of forming a branched polymer by means of chain walking or reincorporation of in situ formed olefinic polymer chains.
