    Abstract: Disclosed is a golf ball cover property improving composition to be added to a thermoplastic polymer material such as a thermoplastic polyurethane material when a golf ball cover is formed from the thermoplastic polymer material, to thereby impart high restitution and excellent scuff resistance to the golf ball cover. The golf ball cover property improving composition contains an isocyanate mixture in which an isocyanate compound (X) having at least two isocyanate groups serving as functional groups in the molecule is dispersed in a thermoplastic resin (Y) which is substantially non-reactive with the isocyanate groups and which has a restitution elastic modulus of at least 45%.

    Abstract: In a solid golf ball comprising an elastic solid core and a resin cover, the cover has a JIS-C hardness of 50-85, and provided that the ball receives a spin rate S1 (rpm) in the dry state and a spin rate S2 (rpm) in the wet state when hit with a short iron having a loft of an 8-iron or greater, the percent spin retention: (S2/S1)null100 is at least 47%. The ball's spin susceptibility when hit with the short iron is not reduced in the dry state or fine weather, nor is noticeably reduced even in the wet state or rain weather. The ball has so high performance that the ball travels a distance as intended, immediately stops on the green, is easy to control and thus, suited for professional and amateur low-handicap golfers.

    Abstract translation: 在包括弹性实心芯和树脂盖的固体高尔夫球中，该盖具有50-85的JIS-C硬度，并且规定球接收干燥状态下的旋转速率S1（rpm），旋转速度S2 当用具有8铁或更高的杆的短铁敲击时，处于湿润状态（rpm），旋转保留百分数：（S2 / S1）×100为至少47％。 用短铁击球时的旋转敏感性在干燥状态或晴朗的天气下不会降低，即使在湿润状态或雨天也不会明显降低。 球具有如此高的性能，使得球按预期行进一段距离，立即停在绿色上，易于控制，因此适合专业和业余的低障碍高尔夫球手。

    Abstract: In a multi-piece solid golf ball comprising a solid core, a mantle and a cover, the solid core is made of a rubber composition comprising a base rubber containing a polybutadiene synthesized using a rare-earth catalyst, a small amount of organic peroxide, an unsaturated carboxylic acid and/or a metal salt thereof, an organic sulfur compound and an inorganic filler. The mantle is made of a thermoplastic resin composition. The cover is made primarily of a mixture of an ionomer resin-containing resin composition and an inorganic filler. This construction provides the golf ball with a combination of outstanding flight performance and soft feel with cover's scuff resistance and crack durability, that is unprecedented.

    Abstract: In a multi-piece solid golf ball comprising a solid core, a mantle and a cover, the solid core is made of a rubber composition that includes (A) a base rubber containing a polybutadiene synthesized using a rare-earth catalyst, (B) a small amount of organic peroxide, (C) an unsaturated carboxylic acid and/or a metal salt thereof, (D) an organic sulfur compound and (E) an inorganic filler. The mantle is made of a thermoplastic resin composition. The cover is made of a material composed of a heated mixture of (F) an olefin/unsaturated carboxylic acid copolymer, an olefin/unsaturated carboxylic acid/unsaturated carboxylic acid ester copolymer, or a metal ion neutralization product thereof, (G) a polyurethane elastomer, and (H) an organic or inorganic basic compound. This construction provides the golf ball with an outstanding flight performance, excellent scuff resistance and a soft feel on impact, and minimizes the decline in rebound by the ball at low temperature.
