ABSTRACT:
A golf ball made by adding bismuth, bismuth alloy or a mixture of bismuth alloy in bismuth to the resin compositions in amounts of 0.5-60 parts by weight per 100 parts by weight of the base resin of the said golf ball, which the carry extends farther than the other common golf balls without raising a hardness. It is because, as molding the said golf ball with the resin compositions which is added bismuth or bismuth alloy, cooling the moldings at a normal temperature after molding, bismuth or bismuth alloy gets solidified and expanded its volume by 3-3.5% and the organic polymeric materials grow dense as much as bismuth expands, that hold a lot of energy. Additionally, since this can be applied to all the core and the cover or selectively to each part, it is possible to make the golf balls with various properties that may give a satisfaction to all sorts of golfers. Furthermore, the golf balls according to the present invention is soft to the touch, which has a good hit feeling.
