摘要： A golf ball includes, as a constituent element thereof, a molded and crosslinked product obtained from a rubber composition containing (A) a base rubber which includes a polybutadiene having a cis-1,4 bond content of at least 60 wt %, (B) an unsaturated carboxylic acid and/or a metal salt thereof, (C) an organosulfur compound, (D) one or more organic peroxide selected from the group consisting of peroxyketals and/or dialkyl peroxides, and (E) one or more organic peroxide selected from the group consisting of hydroperoxides. In the golf ball, the value obtained by subtracting a center hardness of the molded and crosslinked product from a surface hardness thereof, expressed as the JIS-C hardness, is at least 20. The golf ball has a reduced spin rate on shots with a driver and therefore is able to follow a reliable trajectory that does not tend to dip or to rise in a high arc, enabling an increased distance to be achieved.
摘要翻译：高尔夫球作为其构成要素包含由橡胶组合物得到的成型交联物，该橡胶组合物含有（A）含有顺式-1,4键含量为60重量％以上的聚丁二烯的基础橡胶（B ）不饱和羧酸和/或其金属盐，（C）有机硫化合物，（D）一种或多种选自过氧缩酮和/或二烷基过氧化物的有机过氧化物，和（E）一种或多种有机过氧化物选自氢过氧化物。在高尔夫球中，以JIS-C硬度表示的表面硬度减去模塑交联物质的中心硬度所得到的值为至少20.高尔夫球具有降低的喷射速度，驾驶员，因此能够遵循不易于倾斜或以高弧度上升的可靠轨迹，从而能够实现更高的距离。

摘要： A golf ball of the present invention includes: a core located in the center of the golf ball; a cover surrounding the outside of the core and having plural dimples on the surface thereof; and a paint layer surrounding the outside of the cover. The paint layer is formed of a material having rubber elasticity. When the golf ball has a μ hardness and the paint layer has a JIS-C hardness, a ratio Sp of the JIS-C hardness of the paint layer with respect to the μ hardness of the golf ball is at most approximately 15. When the cover has a Shore D hardness, a ratio Sc of the Shore D hardness of the cover with respect to the μ hardness of the golf ball may be at most approximately 25.

摘要： The invention provides a rubber composition for golf balls which includes a base rubber, (B) a metal salt of an unsaturated carboxylic acid and/or an unsaturated carboxylic acid and zinc oxide, (C) an organic peroxide, and (D) from 0.1 to 5 parts by weight of a metal salt of a thiol having the general formula (R—S)nM (wherein R is a monovalent hydrocarbon group having from 12 to 30 carbons, exclusive of aromatic groups; n is an integer such as 1, 2 or 3; and M is a metal) per 100 parts by weight of the base rubber. The golf ball-forming rubber composition of the invention is suitable for pressure molding and has an excellent productivity because it does not lower the rate of vulcanization. The golf ball of the invention, which is formed using the composition, is endowed with an excellent rebound.
