Golf ball compositions for use in ball covers and intermediate layers incorporate a specified block copolymer and are essentially free of ionomeric material. The compositions are outside the scope of those previously considered suitable for use in ball covers and intermediate layers. When used in ball covers, the composition provides for improved ball performance with respect to spin rate, feel, and durability. When used in ball intermediate layers, the composition provides for improved ball performance with respect to spin rate and distance. Also, a method for making a golf ball includes preparing a composition essentially free of ionomeric material including the specified block copolymer, and then incorporating the composition into a golf ball.
