Abstract

The invention is directed to a golf ball comprising a core and a cover, wherein at least one of the core and the cover comprises about 10 wt % or greater of a renewable polymer composition comprising an ultra high molecular weight polyhydroxyalkanoate compound having the formula:—OCR1R2(CR3R4)nCO—wherein n is an integer, and wherein R1, R2, R3 and R4 are selected from the group comprising saturated and unsaturated hydrocarbon radicals, halo- and hydroxy-substituted radicals, hydroxy radicals, halogen radicals; nitrogen-substituted radicals, oxygen-substituted radicals, or hydrogen atoms. In one embodiment, the golf ball also comprises about 90 wt % or less of a non renewable polymer composition. The golf ball may also comprise an intermediate layer disposed about the core and adjacent the cover, wherein at least one of the core, the cover and the intermediate layer comprises the renewable polymer composition. The renewable polymer composition comprises at least one of a flexural modulus of about 50,000 psi or greater and a tensile strength of about 2,000 psi or greater. The at least one of the core and the cover or the intermediate layer may comprise a hardness of from about 50 Shore C to about 90 Shore C.

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application is a continuation of co-pending U.S. patent application Ser. No. 12 / 762,394, filed Apr. 19, 2010, which is a continuation-in-part of co-pending U.S. patent application Ser. No. 12 / 752,423, filed Apr. 1, 2010, which is a continuation of co-pending U.S. patent application Ser. No. 12 / 752,378, filed Apr. 1, 2010.FIELD OF THE INVENTION

[0002] The invention relates to a golf ball including a renewable resource component comprising a biodegradable composition in at least one of the golf ball core (having one or more layers), intermediate layer(s) and cover layer(s). The resulting golf ball possesses desirable playing characteristics such as high resiliency, sustained impact durability, and soft feel, meanwhile protecting the environment over an extended period of time by being decomposable.BACKGROUND OF THE INVENTION

[0003] Golf balls are generally divided into two classes: solid and wound. Solid golf balls include a solid core of ...
