ABSTRACT:
The present invention is directed to a multi-layer golf ball having a core, an intermediate layer and a cover. The intermediate layer has a non-ionomeric composition that includes an ethylene/acid polymer and a non-ionomeric stiffening polymer. The stiffening polymer provides the non-ionomeric composition with a flexural modulus and a hardness that are greater than those of the ethylene/acid polymer.
