Abstract:
A golf ball having a coefficient of restitution of greater than about 0.7 and a compression of at least about 50, wherein the ball comprises a core and a cover having at least one layer disposed concentrically about the core,wherein the layer is formed from a composition comprising a glycidyl polymer composition and a thermoplastic material selected from the group consisting of copolyesters, polyamide homopolymers or copolymers, polyetherester block copolymers, polyesterester block copolymers, polyetheramide block copolymers, polyesteramide block copolymers, polyurethanes, styrene-butadiene copolymers, dynamically vulcanized thermoplastic elastomers, polymers formed using a metallocene catalyst, and blends or copolymers thereof, wherein the glycidyl polymer composition comprises a repeat unit structure consisting essentially of: â€ƒwherein R1, is hydrogen, linear or branched alkyl group having the formula CxH2x+1, aromatic, or alicyclic, where x is an integer from 1 to about 8; R2 is hydrogen, linear or branched alkyl group having the formula CyH2y+1, aromatic, or alicyclic, where y is an integer from 1 to about 20; and n is an integer ranging from 1 to about 6; and wherein the cover is comprised of an outer layer and an inner layer and the composition forms the inner layer.
