    摘要: Multi-piece, solid golf balls having a cover material made from a polyurethane/urea hybrid composition are provided. The balls include an inner core preferably made of polybutadiene and may include at least one intermediate layer disposed between the core and outer cover. The cover materials are prepared by first forming a polyurethane prepolymer which undergoes two curing steps. In the first step, the prepolymer is chemically-cured by reacting it with hydroxyl curing agents, amine curing agents, or mixtures thereof. In the second step, the composition is moisture-cured. The cured material may be used to make a golf ball cover having improved durability, cut/tear resistance, and impact strength.

    摘要: Methods for making polyurea polymer compositions are provided. The methods involve preparing an amine-terminated first prepolymer by reacting isocyanate compound A with a stoichiometric excess of polyamine. The first prepolymer is reacted with a stoichiometric excess of isocyanate compound B to form an isocyanate-terminated second prepolymer. The second prepolymer is reacted with a chain extender. The polymer compositions can be used in different products and are particularly suitable for making golf balls. For example, the polymer compositions can be used to make golf ball covers.

    摘要: Golf balls having a hard outer skin produced from a material that includes crosslinks in both the hard and soft segments of the polymer backbone that improve the crosslink density. Compositions formed from polyurethane and/or polyurea prepolymers that are first cured with a curative blend including an isocyanate-reactive component to crosslink the hard segment and then exposed to a free radical initiator and radiation to crosslink the soft segments are used in an outer layer of a golf ball, a unitary golf ball, or other golf ball constructions.
