A procedure has been developed to make reasonably high molecular weight stereoregular head, tail- polyhydroxypolyamides derived from D-glucaric acid and a series of alkylenediamines. The initial polymerization yields relatively low molecular weight polyamides entitled prepolymers. Further polymerization of these polyamides in a specific solvent solution of dimethyl sulfoxide and ethylene glycol can produce significantly higher molecular weight polyamides, entitled postpolymers. Polymer molecular weights were determined by end group analysis with H1 NMR and a gel permeation chromatographic procedure using a Viscotek GPC triple detector system.
