ABSTRACT:
Thermoplastics with high resilience (high coefficient of restitution) and softness (low Atti compressions) and their use in golf ball components. Melt-processible, highly-neutralized ethylene acid copolymers and process for making them by incorporating an aliphatic, mono-functional organic acid in the acid copolymer and then neutralizing greater than 90% of all the acid groups present.
