Abstract
Curable compositions are disclosed comprising: (A) a carbamate-functional polymer that is the reaction product of a mixture comprising: (1) a polymer that is the reaction product of a mixture comprising: (a) a polyisocyanate and (b) an active hydrogen-containing chain extension agent, and (2) a compound comprising a group that is reactive with said polymer (A) (1) and a carbamate group or group that can be converted to carbamate, and (B) a compound having a plurality of functional groups that are reactive with carbamate groups on said carbamate-functional polymer.
