    摘要： The present invention is directed to a golf ball comprising a shield layer having heat resistant properties to facilitate compression molding of a thermosetting polybutadiene-comprising layer over at least one thermoplastic layer. The invention utilizes a thermoplastic inner core comprising of a low vicat highly neutralized ionomer material having a low melting point of less than 100° C., and a Shore C surface hardness of less than 80 and a compression of less than 70, wherein a shield layer is placed around the low vicat softening point temperature thermoplastic to shield it from the high heat necessary to mold a thermoset material about it.

    摘要： Golf balls containing at least one layer made from a thermoplastic polyurethane or polyurethane-urea that is the reaction product of a polyisocyanate with moisture-resistant polyol and a curing agent are provided. The moisture-resistant polyol may be prepared by dimerizing unsaturated aliphatic monocarboxylic acid or ester containing 10 to 60 carbon atoms followed by reacting it with a monomeric, oligomeric, or polymeric diol. In one preferred version, the moisture-resistant polyol is a branched polyester polyol containing 36 carbon atoms. The composition can be prepared using prepolymer or one-shot manufacturing techniques. The resulting golf ball has desirable playing performance properties including high resiliency, toughness, impact durability, moisture-resistance, and soft feel.

    摘要： The present invention is directed to golf balls having a layer formed from a relatively soft HNP composition and a layer formed from a relatively hard HNP composition. Golf balls of the present invention have at least three layers, including an inner core layer, an outer core layer, a cover, and optionally an intermediate core layer. The present invention is not limited by which golf ball layers are formed from an HNP composition, so long as at least one layer is formed from a relatively soft HNP composition and at least one layer is formed from a relatively hard HNP composition. Relatively soft HNP compositions of the present invention comprise a highly neutralized acid copolymer preferably having a modulus of from 1,000 psi to 50,000 psi. Relatively hard HNP compositions of the present invention comprise a highly neutralized acid copolymer preferably having a modulus of from 25,000 psi to 150,000 psi.
