<p><P>PROBLEM TO BE SOLVED: To offer golf ball composites which have hydrophobicity as well as moisture absorbency tolerance and can realize the optimal combination of physical and performance characteristics, for example, such as a new material compound to be utilized to manufacture a covering layer of golf ball. <P>SOLUTION: A golf ball having a core and a cover layer disposed about the core is disclosed. The core may further include a center and an outer core layer disposed about the center. The cover layer is formed from a composition having multiple reactive and/or non-reactive ingredients. At least one of these ingredients is a hydrogenated telechelic polycarbonate polyahl having a number average molecular weight of 2,000 to 10,000. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
