    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.
