Abstract
A method of preparing a carbamate-functional polymer comprising the steps of providing a hydroxy-functional polymer and reacting a carbamate compound with the hydroxy-functional polymer in the presence of a transcarbamation catalyst, thereby forming a carbamate-functional polymer. The transcarbamation catalyst may be Bi(III) compounds, Zr(IV) compounds, or mixtures of these.
