A polymer and coating composition containing the polymer are provided that are useful in coating applications such as, for example, food or beverage packaging containers. The polymer preferably includes a backbone having one or more polycyclic groups. In one embodiment, the polymer is a polyester and, more preferably, a polyester-urethane polymer. In one embodiment, the one or more polycyclic groups is a tricyclic or higher group.

1. A method, comprising: providing a coating composition comprising: a polymer having a polycyclic group and a backbone that includes both ester and urethane linkages, anda liquid carrier; andapplying the coating composition on a metal substrate prior to, or after, forming the metal substrate into a food or beverage can or a portion thereof. 2. The method of claim 1, wherein the polycyclic group comprises a bridged polycyclic group. 3. The method of claim 1, wherein the polycyclic group comprises a fused polycyclic group. 4. The method of claim 1, wherein the polymer includes at least 10 weight percent of polycyclic groups, based on the weight percent of polycyclic-group-containing monomer relative to the total weight of the polymer. 5. The method of claim 1, wherein the polymer has a glass transition temperature of at least 50° C. 6. The method of claim 1, wherein the polycyclic group includes a heteroatom in a ring of the polycyclic group. 7. A food or beverage can, or a portion thereof, resulting from the method of claim 1, wherein the coating composition is located on an inside surface of the food or beverage can or a portion thereof. 8. The method of claim 1, wherein the polycyclic group comprises a saturated group. 9. The method of claim 8, wherein the polycyclic group comprises a bicyclic group. 10. The method of claim 1, wherein the polycyclic group is an at least tricyclic group. 11. The method of claim 10, wherein the at least tricyclic group includes a substituted or unsubstituted tricyclodecane group. 12. The method of claim 11, wherein the at least tricyclic group is provided by tricyclodecane dimethanol. 13. The method of claim 1, wherein the polymer was formed via reaction of ingredients including a polyisocyanate compound and a polyol. 14. The method of claim 13, wherein the polyisocyanate compound comprises isophorone diisocyanate or hexamethylene diisocyanate. 15. A method, comprising: providing a coating composition comprising: a polymer having an at least tricyclic group and a backbone that includes both ester and urethane linkages, wherein the polymer has a glass transition temperature of at least 50° C. and includes at least 10 weight percent of polycyclic groups, based on the weight percent of polycyclic-group-containing monomer relative to the total weight of the polymer, anda liquid carrier;applying the coating composition on a metal substrate; andforming the metal substrate into a food or beverage can or a portion thereof. 16. A coating composition comprising: a polymer having an at least tricyclic group and a backbone that includes both ester and urethane linkages, wherein the polymer has a number average molecular weight of at least 1,500; anda liquid carrier. 17. The coating composition of claim 16, wherein the polymer is derived from ingredients including a non-aromatic isocyanate compound. 18. The coating composition of claim 17, wherein the polymer has a glass transition temperature of at least 50° C., and where the coating composition includes, based on total weight solids, at least 10% by weight of the polymer. 19. The coating composition of claim 16, wherein the at least tricyclic group is provided by tricyclodecane dimethanol, tricyclodecane diamine, tricyclodecane diisocyanate, or a derivative or mixture there. 20. The coating composition of claim 19, wherein the polymer was formed via reaction of ingredients including a polyisocyanate compound and a polyol, and wherein the polyisocyanate compound comprises isophorone diisocyanate or hexamethylene diisocyanate.
