    • A golf ball having a cover is cast from a castable reactive aliphatic functional composition consisting essentially of: a methylene dicyclohexyl diisocyanate based prepolymer; at least one polyamine/polyamide functional component used as a backbone of the prepolymer; a free isocyanate group; and a curative. The polyamine/polyamide is formed from the condensation reaction of a polyamine and a polyacid, with the equivalent ratio of polyamine to polyacid ranges from 2:1 to 10:1, preferably the ratio is 3:1, and more preferably 2:1. It is preferable that the polyamine be a Jeffamine series D-2000. The polyacid can be chosen from acids such as maleic, adipic, azelaic or sebacic. It is preferable that the prepolymer be a polyurethane or urea. The formulating techniques eliminate the need for post curing when using aliphatic chemistries in golf ball covers.
    • 具有盖的高尔夫球从基本上由以下组成的可浇铸的反应性脂肪族官能组合物铸造:亚甲基二环己基二异氰酸酯基预聚物; 用作预聚物主链的至少一种聚胺/聚酰胺官能组分; 游离异氰酸酯基; 和治疗。 多胺/聚酰胺由多胺和多元酸的缩合反应形成,多胺与多元酸的当量比为2:1至10:1,优选比例为3:1,更优选为2:1。 多胺优选为Jeffamine D-2000系列。 多酸可以选自马来酸,己二酸,壬二酸或癸二酸等酸。 预聚物优选为聚氨酯或脲。 配方技术在高尔夫球罩中使用脂肪族化学物质时,不需要后固化。
