Golf ball compositions and method of making same
First Claim
1. A golf ball having at least one layer formed of a saponified polymer/oxa acid blend comprising from about 65 to about 99 parts of at least one saponified polymer and from about 35 to 1 parts of at least one oxa acid, based on 100 parts by weight of the saponified polymer/oxa acid blend, wherein the at least one layer has a foamed structure.

Abstract
The present invention is directed to a golf ball and to a process for forming a golf ball having at least one layer, where the layer is formed of a saponified polymer/oxa acid blend, having from about 65 to about 99 parts of at least one saponified polymer and from about 35 to 1 parts of at least one oxa acid, based on 100 parts by weight of the saponified polymer/oxa acid blend. The layer may be foamed or unfoamed, and may form at least a portion of any of the cover, the core, or a mantle layer situated between the cover and the core.

forming a polymer comprising a first olefinic monomeric component having from 2 to 8 carbon atoms and a second monomeric component comprising an unsaturated carboxylic acid based acrylate class ester having from 4 to 22 carbon atoms;
applying a sufficient amount of heat to the polymer to convert the polymer to a substantially molten state;
forming a mixture by adding an inorganic metal base to the molten polymer; and
saponifying the mixture to form a saponified polymer, wherein a sufficient amount of the inorganic metal base is added to the molten polymer in forming the mixture to obtain a degree of saponification of the polymer ranging between about 1 and 50 percent.
