简介 Disclosed herein is a two piece solid golf ball consisting of a solid core and a cover, said solid core being formed from a rubber composition composed of a rubber base material of polybutadiene synthesized by using a catalyst of rare earth element, a small amount of organic peroxide, an unsaturated carboxylic acid and/or a metal salt thereof, an organic sulfur compound, and an inorganic filler, and said cover being formed mainly from a mixture of a block copolymer having amino groups at terminals and an ionomer resin. The two-piece solid golf ball is by far superior to conventional ones in flying performance, cover durability, scuff resistance, and soft shot feeling.
