Abstract: 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.
