Abstract:
    A method of preparing a carbamate-functional acrylic polymer is described, comprising the steps of:(A)preparing a mixture comprising:(1)one or more acrylic monomers comprising hydroxy-functional groups or groups or can be converted to hydroxy functional groups,(2)optionally, one or more other addition polymerizable monomers, and(3)a carbamate compound, and(B)heating said mixture in the presence of a free radical initiator and an esterification catalyst, thereby forming a carbamate-functional acrylic polymer.
