Abstract
Golf ball compositions, which contain olefinic polymers produced by use of single-site catalysts. Such polymers can be functionalized with a post-polymerization reaction. The single-site catalyzed polymers may be blended with ionomers, other grafted or non-grafted single-site catalyzed polymers, thermoplastics, non-single-site polymers, or other non-ionomeric polymers. The compositions can be foamed or unfoamed. Golf balls that employ at least one layer of these compositions in any of the golf ball cover, core, or a mantle situated between the cover and the core provide ball properties and performance similar to and in some cases better than the state of the art ionomer based golf balls.
Claims43
A golf ball comprising a cover, a core, and optionally a mantle situated between the cover and the core, wherein at least one of the cover, the core, and the mantle comprises at least one layer formed of a blend comprising:
- a first component of at least one non-metallocene single-site catalyzed polymer;
- and
- a second component of at least one ionomer, non-ionomeric polymer, thermoset polymer, thermoplastic elastomer, or non-single-site catalyzed polymer.
A golf ball comprising a cover, a core, and, optionally, a mantle situated between the cover and the core, wherein at least one of the core, the cover, and the mantle comprises at least one layer formed of a non-metallocene single-site catalyzed polymer and a filler.
A method of manufacturing golf balls comprising:
- providing a core;
- optionally providing a mantle disposed outside the core;
- and
- providing a cover over the core and optional mantle,
- wherein at least one of the cover, the core, and the optional mantle comprises at least one layer formed of a single-site catalyzed polymer blend comprising a first component of at least one single-site catalyzed polymer and a second component of at least one ionomer, non-ionomeric polymer, thermoset polymer, thermoplastic elastomer, or non-single-site catalyzed polymer.
