The present application is directed to a method for preparing an amino-functional polyester, said method comprising: providing a mixture comprising at least one lactone monomer, a catalyst and a polyamine having at least one primary and at least one secondary amine group; and, subjecting said mixture to ring-opening polymerization conditions.

Method for producing functionalized polyesters

The present application is directed to a method for preparing a cyclic carbonate functional polyester, said method comprising: reacting glycerine carbonate with an anhydride to form an Adduct (A); and, reacting said Adduct (A) with at least one polyepoxide compound to form said cyclic carbonate functional polyester (CC-PES). More particularly, the present application is directed to a method for preparing a cyclic carbonate 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; and, D) reacting said epoxy functional polyester with said Adduct (A) to form said cyclic carbonate functional polyester.
