Golf balls comprising elastomer compositions are presently disclosed. These elastomer compositions comprise at least one polyamine having the structure: ##STR00001## where R.sub.1 and R.sub.2 are the same or different radicals chosen from hydrogen and C.sub.1-C.sub.60 organic moieties: Z.sub.1 is chosen from halogens and C.sub.1-C.sub.60 organic radicals: and Z.sub.2, Z.sub.3 and Z.sub.4 are the same or different radicals chosen from hydrogen, halogens, and C.sub.1-C.sub.60 organic radicals. These elastomer compositions can be used in any one or more portions of the golf balls, such as inner core layer, intermediate core layer, outer core layer, intermediate layer, cover, inner cover layer, intermediate cover layer, and/or outer cover layer.
