Four-Piece Golf Balls Including A Crosslinked Thermoplastic Polyurethane Cover Layer |
摘要 |
This disclosure relates to four-piece golf balls having an outer cover layer made from a crosslinked thermoplastic polyurethane elastomer. The crosslinked thermoplastic polyurethane elastomer includes crosslinks located in the hard segments, where the crosslinks being the reaction product of unsaturated bonds located in the hard segments catalyzed by a free radical initiator. The crosslinks may be formed from an unsaturated diol as a chain extender. The unsaturated diol may be trimethylolpropane monoallylether (TMPME). The four-piece golf ball may include an inner core layer formed from a highly neutralized acid polymer composition. The four-piece golf ball may also include an outer core layer formed from a polybutadiene rubber. The golf ball may exhibit a high degree of scuff resistance.
