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.

Polyurea and polyurethane compositions for golf equipment

Curable polyurethane, polyurea and polyurethane/polyurea compositions that are particularly useful as the outer layer and/or at least one inner layer of golf balls, cured compositions, golf balls comprising the cured composition, and methods of increasing the initial velocity of a golf ball using the curable polyurethane, polyurea and polyurethane/poly urea compositions are disclosed.

Compositions useful in golf balls

The present invention is directed to a golf ball that contains an interpenetrating polymer network, or IPN, including at least two polymeric components. These IPNs may be present in any golf ball layer, although in an intermediate or cover layer in one preferred embodiment. The present invention is also directed to methods of forming a golf ball containing an IPN in one or more of the layers.

Golf balls containing interpenetrating polymer networks

Curable polyurethane, polyurea and polyurethane/polyurea compositions that are particularly useful as the outer layer and/or at least one inner layer of golf balls, cured compositions, golf balls comprising the cured composition, and methods of increasing the initial velocity of a golf ball using the curable polyurethane, polyurea and polyurethane/polyurea compositions are disclosed.

A method of forming golf balls with at least a portion formed from polyurethane and polyurea compositions employing a curative blend that includes a pigment, a curing agent, and a compatible freezing point depressing agent so that the curative blend has a lower freezing point than the curing agent by itself and the blend does not lose pigment dispersion upon solidification and subsequent thawing.

Polyurethane compositions for golf balls

Golf balls including cores formed from polybutadiene reaction products having a percent change in dynamic stiffness from 0&#xb0; C. to &#x2212;50&#xb0; C. of less than 130 percent where the reaction products include a resilient polymer component, a crosslinking material, a cis-to-trans catalyst, and a free radical source. The golf balls may be formed with polyurethane covers, covers formed from castable reactive liquid materials, among other materials. The golf balls may also include an intermediate layer.

Thin-layer-covered golf ball with improved velocity

Golf ball compositions, and components formed therefrom, including trifunctional materials, such as trifunctional isocyanates, polyols, and amines, that have improved performance and durability characteristics, e.g., improved heat resistance, improved resiliency, and dimensional stability.

Golf ball compositions with improved temperature performance, heat resistance, and resiliency

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.

Interpenetrating polymer networks using blocked polyurethane/polyurea prepolymers for golf ball layers

Polyurethane and polyurea compositions for golf balls with improved stability of the curative blend, wherein the curative blend includes a pigment, a curing agent, and a compatible freezing point depressing agent so that the curative blend has a lower freezing point than the curing agent by itself and the blend does not lose pigment dispersion upon solidification and subsequent thawing.

Polyurethane and polyurea compositions for golf balls

Polyurethane-based and polyurea-based compositions including modified amine curing agents for use in golf ball layers where modified amine curing agent of the invention allows control of the reaction rate by providing a composition with both primary and secondary amine linkages.

Golf ball layer compositions comprising modified amine curing agents
