Abstract
The present invention provides a golf ball material which is a thermoplastic ionomer blend composition of an acid-containing ethylene-based terpolymer having a weight-average molecular weight Mw of at least about 100,000, an acid-containing ethylene-based copolymer and/or terpolymer having a Mw of about 1,500 to about 95,000, and a low-molecular-weight acid-containing compound having a molecular weight of up to about 1,000, at least some portion of which composition is neutralized. The golf ball material is soft and resilient, and has a good durability and improved moldability.
