Patent ID: 7314906

Claim:
A method of producing a stereoregular head, tail-poly(alkylene D-glucaramide) postpolymer, the method comprising the steps of: a) esterifying an amidoamino acid in an alcohol, wherein the amidoamino acid is derived from D-glucaric acid and an alkylene diamine, the amide bond between C-6 of the glucaryl unit and one nitrogen from one of the amine units of the alkylene diamine. the amidoamino acid having a single amine unit at the alkylene terminus and a carboxylic acid unit at the C-1, D-glucaryl terminus; b) polymerizing the esterified amidoamino acid in a protic solvent in the presence of a tertiary amine to form a stereoregular prepolymer; and c) polymerizing the stereoregular prepolymer in a solvent that is different from the solvent of step b) to form the stereoregular head, tail-poly(alkylene D-glucaramide) postpolymer.
