SOFT AND RESILIENT ETHYLENE COPOLYMERS AND THEIR USE IN GOLF BALLS

Title:

SOFT AND RESILIENT ETHYLENE COPOLYMERS AND THEIR USE IN GOLF BALLS

Document Type and Number:

WIPO Patent Application WO2002079319

Kind Code:

A3

Abstract:

Thermoplastic ionomer compositions having high resilience (high coefficient of restitution) and softness (low Atti compressions) made by highly neutralizing ethylene/carboxylic acid/alkyl (meth)acrylate copolymers that have a high melt index and their use in golf ball components. These soft, resilient ionomers are also made by further melt neutralization or co-neutralization of the high MI ethylene/carboxylic acid/alkyl (meth)acrylate copolymers with an aliphatic, mono-functional organic acid of the acid copolymer and neutralizing to high level.
