摘要： A method of preparing a carbamate functional polymer or oligomer is provided. The method comprises: (a) preparing a reaction mixture comprising a lower alkyl carbamate, a hydroxyl functional polymer or oligomer, and an alcohol different from and having a higher boiling point than an alcohol from which the lower alkyl carbamate is derived; and (b) heating the reaction mixture to form a carbamate functional polymer or oligomer. Also provided is a method of preparing a carbamate functional acrylic polymer by preparing a similar reaction mixture using acrylic monomers containing hydroxyl groups or groups that can be converted to hydroxyl groups and heating the reaction mixture in the presence of a free radical initiator and an esterification catalyst.
