摘要:
The present invention is directed to golf balls having at least one layer formed from a polyurea composition. The polyurea is formed by combining a polyurea prepolymer, a polyamine curative, and a tin catalyst. Golf balls of the present invention include one-piece, two-piece, multi-layer, and wound golf balls. The composition may be present in any one or more of a core layer, a cover layer, or an intermediate layer.
摘要:
Golf balls having at least one layer made from a composition comprising a functionalized polytrimethylene ether-based polyurethane are provided. The composition is the reaction product of a polyisocyanate with polytrimethylene ether glycol and a hydroxyl and/or amine curing agent wherein at least one of the isocyanate compound, polytrimethylene ether glycol compound, or curing agent contains acid, ester, or ionic groups. Blends of polytrimethylene ether glycol with other glycols such as polyester glycol, polycaprolactone glycol, or polycarbonate glycol can be used. The composition can be prepared using prepolymer and one-shot manufacturing techniques. The composition may be used to form any layer in the golf ball structure and the resulting golf ball has improved resiliency and playing performance.
摘要:
Compositions for golf balls that include organically modified silicates and the golf balls formed using the compositions are described. In particular, the compositions of the invention, which are based on a polyurethane and polysiloxane, polyurea and polysiloxane, and/or epoxy and polysiloxane, and, thus, have the benefits of increased COR, adhesion, and shear and impact resistance. The compositions of the invention may be used in any layer of a golf ball, e.g., an outer cover layer or inner cover layer, or may be used as a coating to be disposed over a structural outer layer of a golf ball.
摘要:
The present invention is directed to a method of forming a golf ball that contains an interpenetrating polymer network, or IPN, which includes at least two polymeric systems, in one or more of the layers. The first polymeric system may include a polyurethane-based or polyurea-based system having blocked isocyanate groups and the second polymeric system may include an epoxy-based or acrylic-based system, wherein the two systems are polymerized or cured simultaneously or sequentially to form an IPN.

摘要:
Golf equipment having improved cut and shear resistance that includes a polyurea composition, preferably saturated and/or water resistant, formed of a polyurea prepolymer and a curing agent, wherein the polyurea prepolymer includes an isocyanate and an amine-terminated compound, and wherein the curing agent includes a hydroxy-terminated curing agent, amine-terminated curing agent, or a mixture thereof.
摘要:
The present invention is directed to golf balls having at least one layer which comprises a polymer produced by a process wherein one or more monomers are contacted with a composition comprising the admixture or reaction product resulting from combining (A) a first olefin polymerization catalyst, (B) a second olefin polymerization catalyst capable of preparing polymers differing in chemical or physical properties from the polymer prepared by the first olefin polymerization catalyst under equivalent polymerization conditions, and (C) a chain shuttling agent. Golf balls of the present invention include one-piece, two-piece, and multi-layer golf balls. In two-piece and multi-layer golf balls of the present invention, the polymer may be present in a core layer, a cover layer, an intermediate layer (in the case of multi-layer balls), or a combination thereof.

摘要:
Golf balls that have at least one layer formed from a cationic polyurea material. In particular, the compositions of the invention, which include a polymer backbone including urea linkages with cationic groups, may be formed from an isocyanate-containing component and an isocyanate-reactive component, at least one of which includes precursor cationic groups, in the presence of an alkylating, quaternizing, or ternarizing agent.
