wherein the ratio of hydroxyurethane linkages to urethane linkages is 50:1 to 2:1.
2. The golf ball of claim 1 , wherein the ratio of hydroxyurethane linkages to urethane linkages is 50:1 to 10:1.
3. The golf ball of claim 1 , wherein the amine-terminated component comprises a solvent.
4. The golf ball of claim 1 , wherein the cyclic carbonate comprises a five-membered cyclic carbonate, a six-membered cyclic carbonate, or a combination thereof.
5. The golf ball of claim 1 , wherein the amine-terminated component comprises two primary functional amines at terminal ends of a polyol backbone.
