Problems solved by technology

However, polyurea compositions can be difficult to process during golf ball manufacturing.
For example, many polyurea systems have rapid viscosity build-up upon mixing due to their auto-catalytic nature, which does not allow enough time to adequately mix the materials and mold the parts.

Embodiment Construction

[0006]By the present invention, it has been found that the reactions of linear and cycloaliphatic-based polyisocyanates and cycloaliphatic amine curing agents can be effectively inhibited by the addition of tin compounds.

[0007]The compositions of the present disclosure typically comprise a reaction product of a polyisocyanate and one or more reactants. In one example, the reaction product can be a polyurethane formed from a polyurethane prepolymer and a curative, the polyurethane prepolymer being a reaction product of a polyol telechelic and an isocyanate. The polyol telechelic comprises at least two terminal hydroxyl end-groups that are independently primary, secondary, or tertiary. The polyol telechelic can further comprise additional hydroxyl groups that are independently located at the termini, attached directly to the backbone as pendant groups, and / or located within pendant moieties attached to the backbone. The polyol telechelic can be α,ω-hydroxy telechelics having isocyanat...

Abstract

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of U.S. patent application Ser. No. 11 / 162,544, filed Sep. 14, 2005, which is a continuation-in-part of U.S. patent application Ser. No. 10 / 859,557, filed Jun. 2, 2004, now U.S. Pat. No. 7,105,628, the entire disclosures of which are hereby incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention is directed to polyurea compositions formed by combining a polyurea prepolymer, a polyamine curative, and a tin catalyst. The present invention is also directed to the use of such compositions in golf equipment.BACKGROUND OF THE INVENTION[0003]Polyureas are known to be potentially useful materials for golf ball covers. However, polyurea compositions can be difficult to process during golf ball manufacturing. For example, many polyurea systems have rapid viscosity build-up upon mixing due to their auto-catalytic nature, which does not allow enough time to adequately mix the mater...
