Abstract
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.
Claims15
A method for preparing a cyclic carbonate functional polyester, said method comprising
- (1) reacting a glycerine carbonate with an anhydride to form an Adduct (A) having a general structure of Formula (I)
- in which n is 1, 2 or 3,
- (2) reacting said Adduct (A) with at least one polyepoxide compound to form an Adduct (B) having a general structure of Formula (II)
- in which R1 represents a residue of a dihydric phenol or dihydric alcohol, and n is 1, 2 or 3, and
- (3) reacting said Adduct (B) with at least one polycarboxylic acid to form said cyclic carbonate functional polyester.
