COMPOSITIONS INCORPORATING ETHYLENE ACID (E/X) IONOMERS AND NON-IONOMERIC SOFTENING POLYMERS FOR GOLF BALL CONSTRUCTIONS AND METHODS RELATING THERETO |
摘要 |
A golf ball comprising a core and a cover disposed about the core; wherein at least one of the core and the cover comprises a tri-blend composition of the non-E/X/Y type (TBC) formed from a blend of an ethylene acid (E/X) ionomer, a non-ionomeric softening copolymer (NISC) and a low viscosity component (LVC). A portion of the TBC comprising the ethylene acid (E/X) ionomer and the NISC has a Melt Flow Index MF1 and a CoR1 and the TBC has a Melt Flow Index MF2 and a CoR2 such that MF2>MF1 and CoR1 and CoR2 differ by less than about 0.1. In one embodiment, the TBC has a composition property relationship ΔCoR/ΔMFI≦˜10, wherein ΔCoR is the amount by which CoR1 and CoR2 differ, and ΔMFI=(MFI2−MFI1). In one embodiment, the TBC comprises a phase-separated blend. The invention is also directed to a method of making the golf ball. |
