摘要：
A golf ball includes a cover material containing a thermoplastic polyurethane composition which may be crosslinked post-mold by applying a radiation source such as ultraviolet light. The thermoplastic polyurethane composition may be crosslinked under controlled conditions selected to yield golf balls exhibiting desired physical properties and performance characteristics, such as hardness, spin, feel, and distance. In some examples, the golf ball contains one or more additional components, such as a UV curable topcoat, that may be simultaneously treated by the radiation source, thus improving processing efficiency.
