The present application is directed to a method for preparing a cyclic carbonate functional polyester, said method comprising the stages of (A) reacting glycerine carbonate with an anhydride to form an Adduct (A), (B) reacting said Adduct (A) with at least one polyepoxide compound to form an Adduct (B), and (C) reacting said Adduct (B) with at least one polycarboxylic acid to form said cyclic carbonate functional polyester.

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.
