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 polymer blend comprising an oxa ester or a saponified polymer/oxa ester 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 ester, based on 100 parts by weight of the saponified polymer/oxa ester 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.

55. A method for forming a golf ball, the method comprising:
-
forming a polymer blend, which comprises at least one oxa ester; and
forming at least one layer of a golf ball from the polymer blend. - View Dependent Claims (56, 57, 58)
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;
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; and
blending the saponified polymer with the at least one oxa ester to form the polymer blend.

57. The method according to claim 56, further comprising forming the mixture of the inorganic metal base and the molten polymer at a temperature such that the mixture has a viscosity that remains substantially unchanged from that of the molten polymer.
-
58. The method according to claim 56, further comprising forming the polymer with 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.
