ABSTRACT:
Disclosed herein is a golf ball cover composition comprising a combination of ionomer, ethylene-propylene rubber, and copolymer formed from (a) an .alpha.-olefin having two to eight carbon atoms, (b) an unsaturated monomer of the acrylate ester class having from 1-21 carbon atoms, and (c) an acid which includes at least one member selected from the group consisting of .alpha., .beta.-ethylenically unsaturated mono- and dicarboxylic acids, the weight ratio of the ethylene-propylene rubber to copolymer of .alpha.-olefin, acrylate ester and acid being in the range of 25:75 to 75:25. The novel cover composition enables the production of a golf ball having a high coefficient of restitution and a very soft cover with excellent cut resistance.
