| abstract |
The invention provides a golf ball composed of, at least in part, a molded and crosslinked material obtained from a rubber composition made of a base rubber, a filler, an organic peroxide, an α,β-unsaturated carboxylic acid and/or metal salt thereof, and a copper salt of a saturated or unsaturated fatty acid. The molded rubber composition has a very high rebound, and is thus useful as a golf ball core for achieving an excellent flight performance. |
