Title: METHOD FOR PRODUCING FUNCTIONALIZED POLYESTERS
Abstract:
The present application is directed to a method for preparing an amino and hydroxyl-functional polyester, said method comprising: i) preparing an unsaturated polyester by the polycondensation reaction, optionally in the presence of a catalyst, of reactants comprising or consisting of at least one diol and at least one α,β- ethylenically unsaturated dicarboxylic acid or anhydride thereof, wherein said polycondensation reaction is characterized by a stoichiometric excess of hydroxyl groups to carboxyl groups; and, ii) reacting, by conjugate addition, said unsaturated polyester with at least one polyamine, said polyamine having at least one primary amine group and at least one secondary amine group.
