Abstract
Golf ball comprising thermoplastic blend of (i) ionomer(s); (ii) different thermoplastic polymer(s); (iii) reactive crosslinker(s) consisting of maleic group-modified polymer(s), and/or glycidyl (meth)acrylate-modified polymer(s) (“PGM”); and (iv) catalyst(s); ionomer present in amount of about 45 wt % or greater, and PGM present in amount of from about 2 wt % to about 35 wt %. Thermoplastic polymer may be present in amount of from about 8 wt % to about 50 wt %; or from about 25 wt % to about 45 wt %; or from about 35 wt % to about 50 wt %. Amount of ionomer may be greater than amount of thermoplastic polymer. Thermoplastic polymer may be a polyurethane present in amount of greater than 20 wt % and up to about 40 wt %; and the PGM is present in amount of from about 5 wt % to about 30 wt %. In some embodiments, PGM is present in an amount of from about 15 wt % to about 35 wt %.
