Title: Golf ball forming compositions comprising polyamide

Abstract: The present invention relates to a golf ball comprising a core layer, atleast one intermediate layer, and a cover layer, wherein the core layer orthe at least one intermediate layer are formed from compositionscomprising a polyamide, in the form of a homopolymer, a copolymer, ormixtures thereof. The compositions comprise about 1 to about 99 weightpercent of at least one nonionomer polymer and about 99 to about 1 weightpercent of at least one polyamide polymer. The polyamides of the presentinvention comprise polyamides and polyamide copolymers, such as nylons,nylon copolymers, and nylon block copolymers. The nonionomer polymercomprises a nonionomer thermoplastic elastomer or a nonionomerthermoplastic. The present invention also relates to a method of making agolf ball comprising forming a golf ball core, preparing a compositioncomprising about 1 to about 99 weight percent of at least one nonionomerpolymer and about 99 to about 1 weight percent of at least one polyamidepolymer, and molding the blend around the golf ball core to form the golfball.
