Abstract
The invention concerns a golf ball constituted of a three part structure, constituted of an elastomer core, an intermediate layer, and a thermoplastic envelope. The intermediate layer is made of a thermoplastic material containing at least 10%, and preferably at least 35% of ether block copolymer. The material may also be advantageously constituted of ether block copolymer to which is added 0 to 90% of ionomer(s) with respect to the total weight of the compound.
