Abstract
The present invention is directed to a solid, non-wound, golf ball comprising two or more core components, and a cover component. The core components comprise i) a small, inner, high density, spherical center component comprising a blend of powdered metal and a first matrix material comprising polybutadiene and polyisoprene; and, ii) an outer core layer disposed about the spherical center component, formed from a second matrix material selected from the group consisting of a thermoset material, a thermoplastic material, or combinations thereof. The golf ball may further comprise a second or additional outer core layer(s) that surround the first outer core layer. Preferably, the inner, high density, center component is produced without the use of a crosslinking agent or coagent, which is the reaction product of an unsaturated carboxylic acid or acids and an oxide or carbonate of a metal such as zinc. The cover may be single or multi-layered. For a multi-layered cover, the inner cover layer is comprised of a low or high acid ionomer or ionomer blend and the outer cover layer is comprised of a soft, very low modulus ionomer or ionomer blend, or a non-ionomeric thermoplastic elastomer …
