Abstract
The present invention is directed to a golf ball and a to a process for forming a golf ball having least one layer, where the layer is formed of a saponified polymer/polyamide blend, having from about 1 to about 99 parts of at least one saponified polymer and from about 99 to 1 parts of at least one polyamide polymer, based on 100 parts by weight of the saponified polymer/polyamide blend. The layer may be foamed or unfoamed, and may form at least a portion of any of the cover, the core, or an intermediate layer situated between the cover and the core.
Claims59
A golf ball having at least one layer, said layer comprising a saponified polymer/polyamide blend comprising at least one saponified polymer and at least one polyamide polymer, wherein the saponified polymer comprises:
- a first olefinic, monomeric component having from 2 to 8 carbon atoms;
- a second monomeric component comprising an unsaturated carboxylic acid based acrylate class ester having from 4 to 22 carbon atoms and at least one ester group, wherein at least a portion of said at least one ester group has been saponified with an inorganic metal base;
- and
- a third monomeric component selected from the group consisting of carbon monoxide, sulfur dioxide, an anhydride monomer, an unsaturated monocarboxylic acid, an olefin having from 2 to 8 carbon atoms and a vinyl ester or a vinyl ether of an alkyl acid having from 4 to 21 carbon atoms.
A golf ball comprising a cover layer, a core layer and at least one intermediate layer situated between the cover layer and the core layer, wherein at least one of said layers comprises a blend of at least one saponified polymer and at least one polyamide polymer, wherein the polyamide polymer is selected from the group consisting of polyamide 6, polyamide 11, polyamide 12, polyamide 4,6, polyamide 6,6, polyamide 6,9, polyamide 6,10, polyamide 6,12, polyamide 6/6,6, polyamide 6,6/6,10 polyamide 6/6,T, polyamide 6/6,6/6,10, and mixtures thereof.
A golf ball having at least one layer, said layer comprising a saponified polymer/polyamide blend comprising from about 1 to about 99 parts of at least one saponified polymer and from about 99 to about 1 parts of at least one polyamide polymer, based on 100 parts by weight of the saponified polymer/polyamide blend, wherein the polyamide polymer is selected from the group consisting of polyamide 6, polyamide 11, polyamide 12, polyamide 4,6, polyamide 6,6, polyamide 6,9, polyamide 6,10, polyamide 6,12, polyamide 6/6,6, polyamide 6,6/6,10, polyamide 6/6,T, polyamide 6/6,6/6,10 and mixtures thereof.
