Castable golf ball components using acrylate functional resins

A golf ball comprising a core and a cover, wherein the cover is cast from a composition comprising:

• a polyurea backbone formed from the reaction of at least one isocyanate and at
• least one amine-terminated compound;
• at least one unsaturated acrylate functional segment reacted with the polyurea backbone;
• and
• at least one free radical initiator;
• wherein the at least one unsaturated acrylate functional segment comprises
• amine-terminated acrylate, amine-terminated methacrylate, amine-terminated methyl methacrylate, amine-terminated ethyl acrylate, amine-terminated ethyl methacrylate, amine-terminated butyl acrylate, amine-terminated butyl methacrylate, amine-terminated glycidyl acrylate, amine-terminated glycidyl methacrylate, or mixtures thereof.
