Abstract
Abstract This invention relates to a composition for forming a unitary molded golf ball and which composition comprises essentially highly resilient polybutadiene rubber, a cross linking agent, such as trimethylol propane trimethacrylate, a curative agent, non-black reenforcement and/or filler material, and a high density olefin, specifically an ultra high molecular weight linear polyethylene, which composition can be molded to form a golf ball having highly desirable properties.
