ABSTRACT:
Compositions comprising amino acid terminated polyesters having predetermined monomeric sequence are produced by stepwise addition of monomeric hydroxyacids to an amine to form a growing polymeric chain. Included herein are various amino acid terminated polyesters having predetermined monomeric sequence, methods for their production and use as well as articles formed from said compositions.
