Abstract
Disclosed herein is a multi-layer golf ball having a central core, an inner cover layer containing a non-ionomeric polyolefin material, preferably a plastomer, and an outer cover layer comprising a thermoplastic material. The combined thickness of the inner and outer cover layer preferably is at least about 0.10 inches. The golf ball has a coefficient of restitution of at least about 0.780. When the inner cover layer contains a non-ionomeric material such as a metallocene-catalyzed polyolefin and the outer cover layer contains ionomer, the golf ball of the invention can be configured to have playability properties comparable to those of golf balls which contain substantially higher quantities of ionomer. A method for forming the golf ball described above also is disclosed.
