<p>This invention provides a golf ball constituting or having a core layer, intermediate layer and/or cover layer consisting in whole or in part of a poly(trimethylene terephthalate) composition. The invention also provides methods for making such a ball. The compositions of the core layer, intermediate layer and/or cover layer may be foamed or unfoamed. The poly(trimethylene terephthalate) may comprise from about 1 to about 100 percent by weight of the core layer, intermediate layer and/or cover layer. In addition, the poly(trimethylene terephthalate) material may be blended with conventional materials employed to form golf ball cores, intermediate layers and/or covers.</p> |
