A golf ball including a core and a cover layer, where the cover layer includes a curing agent and a polyurethane/urea hybrid prepolymer formed from a polyisocyanate and a monodisperse heterotelechelic polymer having a polydispersity of from about 1.0 to about 1.3, and having the formula: T-Z-Qn-C-Y-W where C is a hydrogenated or unsaturated block derived by anionic polymerization of at least one monomer selected from the group consisting of conjugated dienes, alkenyl-substituted aromatic hydrocarbons, and mixtures thereof; Y and Z are independently branched or straight chain hydrocarbon connecting groups which contains 3-25 carbon atoms optionally substituted with aryl or substituted aryl containing lower alkyl, lower alkylthio, or lower dialkylamino groups; Q is an unsaturated or hydrogenated hydrocarbyl group derived by incorporation of at least one compound selected from the group consisting of conjugated diene hydrocarbons, alkenyl-substituted aromatic hydrocarbons, and mixtures thereof; T and W are different and are selected from either oxygen or nitrogen; and n is an integer from 0 to 5.
