Preparation and Characterization of Copolymer of Lactic Acid and N, N-Bis (hydroxyethyl) Glycin

Abstract:

Branched copolymer of lactic acid/bicine (N, N-bis (hydroxyethyl) glycin) was prepared directly by melt polycondensation from lactic acid and bicine. The branched structure of copolymer of lactic acid/bicine was characterized by 1H NMR and intrinsic viscosity. Although the molecular weigh of copolymer was lower than that of homopolymer of lactic acid, the hydroxyl number of the copolymer was higher than that of homopolymer. All the data indicated the molecule structure of copolymer was branched. Compared with homopolymer of lactic acid, the crystallinity of the branched copolymer decreased and the thermal stability increased.
