    摘要： The present invention is a multi-piece golf ball having a casing layer comprising of a single high acid based ionomer that is blended with an ultra high melt flow index maleic anhydride terpolymer with a melt flow index of at least 70 g/10 min. at 190° C. The maleic anhydride terpolymer comprises a copolymer of ethylene-alkyl acrylate-maleic anhdydride. The alkyl acrylate is selected from methyl, or ethyl, or propyl, or butyl, or pentyl acrylate. The maleic anhydride content in the terpolymer is 1 to 4% of the total blend by weight. The single high acid ionomer such as a copolymer of ethylene-acrylic or methacrylic is partially neutralized with a suitable cation such as lithium, sodium, magnesium, zinc, or potassium.

    摘要： A golf ball having a core, and at least one layer about the core, wherein the core or the layer is formed from partially or fully neutralized butyl ionomers or their blends to improve the resiliency and impact durability over a conventional butyl rubber. The core comprises a thermoplastic material, a thermoset material, or a rubber-based material, while at least one layer is formed from a composition comprising a partially or fully neutralized butyl rubber ionomer. The butyl rubber ionomer comprises repeating units derived from at least one isoolefin monomer, at least 0.5 mol % of repeating units derived from at least one multiolefin monomer, at least 0.5 mol % of repeating units derived from an allylic halide, and at least 0.5 mol % of an ionomeric moiety. The isoolefin comprises isobutylene, the multiolefin comprises isoprene and the allylic halide comprises a bromide.
