Abstract

The present invention relates to improved cover compositions for golf ball construction. The-cover compositions comprise a blend of (1) modified thermoplastic rubber elastomers, wherein the thermoplastic rubber elastomers are modified with a polar group, such as malefic anhydride, and (2) ionomer resins.

In addition, the present invention is directed to golf balls produced utilizing the improved cover compositions. The golf balls exhibit properties of enhanced playability without sacrificing distance and/or durability.
