Patent number: 6482109Abstract: 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.Type: GrantFiled: November 29, 2000Date of Patent: November 19, 2002Assignee: Bank of America, N.A.Inventors: R. Dennis Nesbitt, Mark L.

Patent number: 6435983Abstract: The present invention is directed to an improved multi-layer golf ball comprising a core, an inner cover layer and an outer cover layer. The inner cover layer is comprised of a relatively hard cover material. The outer cover layer is comprised of a soft, very low modulus ionomer or ionomer blend, or a non-ionomeric thermoplastic elastomer such as polyurethane, polyester or polyesteramide. The outer cover layer exhibits a Shore D hardness of less than 50D. The golf ball may further comprise an optional mantle layer, which may include one or more filler materials. Filler material may be incorporated in one or more of the core, inner cover layer, or outer cover layer. The resulting multi-layered golf ball of the present invention exhibits reduced slippage between the ball and club face, and therefore, relatively high spin rates.Type: GrantFiled: November 29, 2000Date of Patent: August 20, 2002Assignee: Spalding Sports Worldwide, Inc.Inventors: Thomas J.

Publication number: 20010016524Abstract: The present invention is directed to improved golf ball compositions in which the balls have low spin and excellent distance. The balls contain tungsten or another high density filler in a solid, central core in order to enhance coefficient of restitution, and have very high quantities of whitening agent in the outer cover layer to increase the moment of inertia and thus reduce spin. This results in a golf ball exhibiting enhanced distance while maintaining good durability.Type: ApplicationFiled: December 22, 2000Publication date: August 23, 2001Inventors: Michael J. Sullivan, R.
