摘要:
A golf ball having a core comprising metallocene catalyzed polyolefin and having a PGA compression of no greater than about 85 and a multi-layered cover disposed about the core having a thickness of at least about 3.6 mm is described. A golf ball is also described having a core with a PGA compression of no greater than about 85 and a multi-layer cover with a thickness of at least 3.6 mm (0.142 inches) and a Shore D hardness of at least about 60 wherein at least one layer of the multi-layered cover comprises a high acid ionomer resin having at least 16% by weight of an alpha, beta-unsaturated carboxylic acid. The combination of a core with a thick, relatively hard multi-layer cover results in a ball having better distance than conventional golf balls having a comparable coefficient of restitution.
