Abstract
A low compression, resilient golf ball having a center including a material formed from the conversion reaction of sufficient amounts of polybutadiene, a free radical source, and a cis-to-trans catalyst to convert a portion of cis-isomer to trans-isomer in the polybutadiene, wherein said material has an amount of trans-isomer greater than the amount of trans-isomer present before the conversion reaction, and wherein the reaction product is susbstantially free of antioxidant.
Claims31
A golf ball having a cover and a core, wherein the core comprises a material formed from the conversion reaction of polybutadiene, a free radical source, and a cis-to-trans catalyst, wherein the conversion reaction occurs at a sufficient temperature to form a polybutadiene reaction product comprising:
- a second amount of trans-isomer content greater than the first amount of trans-isomer content.
A golf ball having a cover and a core, wherein the core comprises a material formed from the conversion reaction of an amount of polybutadiene comprising a first trans-isomer content, a free radical source, and a cis-to-trans catalyst comprising a Group VIA component, wherein the conversion reaction occurs at a sufficient temperature to form a polybutadiene reaction product comprising:
- a second amount of trans-isomer content greater than the first amount of trans-isomer content.
A golf ball having a cover and a core, wherein the core comprises a material formed from the conversion reaction of an amount of polybutadiene comprising a first trans-isomer content, a free radical source, and a cis-to-trans catalyst comprising a Group VIA component, wherein the conversion reaction occurs at a sufficient temperature to form a polybutadiene reaction product comprising:
- a second amount of trans-isomer content at an exterior surface on the core greater than the first amount of trans-isomer content;
- and
- a third amount of trans-isomer content at an interior location in the core greater than the first amount of trans-isomer content.
