Abstract
The invention provides a golf ball comprising a core of at least one layer, a cover of at least one layer, and optionally an intermediate layer therebetween, characterized in that at least one layer of the core, cover and intermediate layer is formed of a golf ball-forming resin composition comprising, in admixture, (A) 100 parts by weight of a polyether ester block copolymer composed primarily of (a) high-melting crystalline polymer segments made of crystalline aromatic polyester units and (b) low-melting polymer segments made of aliphatic polyether units and (B) 0.05–10 parts by weight of a polyisocyanate compound. Using the golf ball-forming resin composition which has flexibility and high rebound resilience and is fully wear resistant, the inventive golf ball is improved in travel distance, feel, scuff resistance and impact durability.
