Patent ID: 6838501

Claim:
A golf ball material comprising a mixture which is composed of: 100 parts by weight of a resinous component consisting essentially of a base resin having (a) an olefin-unsaturated carboxylic acid binary random copolymer or a metal ion-neutralized olefin-unsaturated carboxylic acid binary random copolymer or both, blended with (b) an olefin-unsaturated carboxylic acid-unsaturated carboxylate ternary random copolymer or a metal ion-neutralized olefin-unsaturated carboxylic acid-unsaturated carboxylate ternary random copolymer or both, and (e) a non-ionomer thermoplastic elastomer, said base resin and said elastomer being blended in a weight ratio of 99:1 to 50:50; (c) 5 to 80 parts by weight of a fatty acid or fatty acid derivative or both, having a molecular weight of 280 to 1,500; and (d) 0.1 to 10 parts by weight of a basic inorganic metal compound capable of neutralizing acidic groups left unneutralized in the base resin and component (c).
