Catalyst compositions comprising chain shuttling agents and the use thereof to produce golf ball compositions

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 a first monomer selected from the group consisting of propylene and 4-methyl-1-pentene, and one or more addition polymerizable comonomers other than the first monomer, 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.

A golf ball having at least one layer formed from a composition comprising a multi-block copolymer selected from the group consisting of maleic anhydride grafted ethylene-butene multi-block copolymers and maleic anhydride grafted ethylene-octene multi-block copolymers, wherein the multi-block copolymer is produced by a process comprising:

• contacting one or more addition polymerizable monomers 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.
