ABSTRACT:
The present invention is directed toward more durable golf ball cores and more durable golf balls. The golf balls of this invention comprise a cover and a core wherein the core may further comprise a center and one or more layers of a mantle disposed between the center and the cover. The core, the mantle or the layers of the mantle, comprise a mixture of one or more thermoset rubber materials and at least one compatible, modified, non-ionic polyolefin. The non-ionic polyolefin that is modified may be a homopolymer, copolymer, terpolymer, block copolymer or a mixture thereof that is present at about 0.5 to about 10 parts per hundred of the thermoset rubber material used in the core or core layer.
