Patent ID: 10773132

Abstract:
Golf ball incorporating layer(s) of a mixture consisting of: i) ionomer(s); ii) ethylene propylene rubber(s)(EPR(s)); iii) polymeric epoxy crosslinker(s); and iv) compatibilizing polymer(s). The ionomer(s) and EPR(s) may be included in a blend in a wt % ratio of from about 85:15 to 55:45; the at least one polymeric epoxy crosslinker and compatibilizing polymer may be included in amounts, based on 100 parts of the blend, of from about 2.0 to about 10.0 parts; and from about 1.0 to about 10.0 parts, respectively. Each ionomer, EPR, polymeric epoxy crosslinker, and compatibilizing polymer has a density less than 1.0 g/cm3. The mixture is melt processable/moldable without meanwhile sacrificing target CoR, DCM compression, Shore D hardness, and Shore C hardness.
