The present invention is directed to a method for preparing an amino and hydroxy-functional polyester, said method comprising: reacting glycerine carbonate with an anhydride to form an Adduct (A); reacting said Adduct (A) with at least one polyepoxide compound to form said cyclic carbonate functional polyester (CC-PES); and, reacting said cyclic carbonate functional polyester with at least one aliphatic, alicyclic, heterocyclic or aromatic amine containing at least two primary and / or secondary amine groups. More particularly, the present application is directed to a method for preparing an amino and hydroxy-functional polyester, said method comprising the stages: A) reacting glycerine carbonate with an anhydride to form an Adduct (A); B) providing a polycarboxylic acid; C) reacting said polycarboxylic acid with at least one diglycidyl ether to form an epoxy functional polyester; D) reacting said epoxy functional polyester with said Adduct (A) to from a cyclic carbonate functional polyester; and, E) reacting said cyclic carbonate functional polyester with at least one aliphatic, alicyclic, heterocyclic or aromatic amine containing at least two primary and / or secondary amine groups.
