Abstract

Polydepsipeptides, copolymers of α - amino acids and α - hydroxy acids, could prove to be a valuable new class of synthetic BIODEGRADABLE polymers. In this paper, steps in synthesis of poly (DL-LACTIDE-co-3, 6-DIMETHYLMORPHOLINE-2,5-dione) from dl-Iactide and DL-3,6-DIMETHYLMORPHOLINE-2,5-dione was explained. dl -Lactide was synthesized from lactic acid. In the reaction of 2-bromopropionyl chloride and DL-ALANINE, N-(2-bromopropionyl)-dl-alanine was prepared and this material was converted to its salt and finally this salt was converted to 3, 6-DIMETHYLMORPHOLINE-2, 5-DIONE in a sublimer. These two monomers, that is, dl -lactide and DL-3, 6-DIMETHYLMORPHOLINE-2, 5-DIONE was polymerized by RING-OPENING POLYMERIZATION. FT-IR, 1H NMR, 13C NMR Spectra were used for structure elucidation of all intermediate compounds and final product.
