| 摘要 |
The present invention relates to a golf ball comprising a core layer, at least one intermediate layer, and a cover layer, wherein the core layer or the at least one intermediate layer are formed from compositions comprising a polyamide, in the form of a homopolymer, a copolymer, or mixtures thereof. The compositions comprise about 1 to about 99 weight percent of at least one nonionomer polymer and about 99 to about 1 weight percent of at least one polyamide polymer. The polyamides of the present invention comprise polyamides and polyamide copolymers, such as nylons, nylon copolymers, and nylon block copolymers. The nonionomer polymer comprises a nonionomer thermoplastic elastomer or a nonionomer thermoplastic. The present invention also relates to a method of making a golf ball comprising forming a golf ball core, preparing a composition comprising about 1 to about 99 weight percent of at least one nonionomer polymer and about 99 to about 1 weight percent of at least one polyamide polymer, and molding the blend around the golf ball core to form the golf ball. |
