Golf ball incorporating at least one layer of plasticized neutralized acid polymer composition containing low molecular weight acid wax(es) as sole acid polymer component and low molecular weight non-acid wax(es) in the non-acid polymer component

摘要

Golf ball comprising layer(s) comprised of plasticized neutralized acid polymer composition consisting of mixture of: (a) low molecular weight acid-containing wax(es); (b) non-acid-polymer(s) including at least one low molecular weight non-acid wax such as high density oxidized polyethylene homopolymers; ethylene maleic anhydride copolymers; polypropylene maleic anhydride copolymers; polypropylene homopolymers; ethylene-vinyl acetate copolymers; high density oxidized homopolymers; oxidized copolymers; polyethylene micronized waxes; polytetrafluoroethylene micronized waxes; emulsifiable low molecular weight non-acid waxes; non-emulsifiable low molecular weight non-acid waxes; and/or chemically modified low molecular weight non-acid waxes; (c) organic acid(s) or salt thereof; and (d) plasticizer(s). Molecular weight of each low molecular weight acid-containing wax is about 500 to 7000, or up to 30,000. Interactions between components (a), (b), (c) and (d) advantageously produce layer of ionomeric material having heat stability, processability, and well-retained durability, adhesion, CoR, compression and softer feel without need for blending high and low molecular weight acid-containing polymer(s).
