Abstract
The present invention is directed to golf ball cover compositions containing blends of high or low carboxylic acid based copolymers and ethylene copolymers such as ethylene alkyl acrylates. The carboxylic acid groups of the blends are neutralized with metal cations. Golf balls produced with the cover molded thereon exhibit desired properties of distance and high coefficient of restitution without substantially sacrificing and/or improving characteristics like playability and durability when compared to existing covers comprising ionomeric resin blends.
Claims15
A golf ball having a core and a cover wherein said cover comprises 30 to 90% of a neutralized ethylene/acrylic acid copolymer and 10-70 parts by weight of an ethylene alkyl acrylate copolymer containing up to 30% by weight of the alkyl acrylate.
A golf ball having a core and cover wherein the cover comprises of a neutralized acrylic, acid/ethylene copolymer having from about 9 to about 25% acrylic acid and 10-70 parts by weight of an ethylene/alkyl acrylate copolymer containing up to 30% of an alkyl acrylate selected from the group consisting of methyl acrylate, butyl acrylate, and ethyl acrylate.
A golf ball comprising a core and a cover wherein said cover comprises 30 to 90 parts by weight of a 10 to 90% neutralized carboxylic acid/ethylene copolymer and 10 to 70 parts by weight of an ethylene/alkyl acrylate copolymer containing up to 30% by weight of the alkyl acrylate.
