Abstract

Polyamides and poly(ester amide)s which contain glycine residues as a comonomer show unique features. In collaboration with Professor M. Goodman we carried out studies on low molecular weight models which allow a structural analysis with atomic detail. In this way, sequential polyamides constituted by glycine and ω‐amino acids may adopt new structures characterized by a network of intermolecular hydrogen bonds that are established along three directions at 120°. This peculiar structure is based on the conformational preferences of glycine residues. X‐ray and electron microscopy studies on poly(ester amide)s indicate a structure constituted by a stacking of hydrogen bonded sheets. Differences have been found in the shift between consecutive sheets. Copyright © 2005 European Peptide Society and John Wiley & Sons, Ltd.

## Abstract Poly(esters amide)s from adipic anhydride and __α__,__ω__‐amino alcohols were obtained by polycondensation of __α__‐carboxyl‐__ω__‐hydroxyl amides under mild conditions in solution or by bulk polycondensation at elevated temperatures. For the polycondensation in bulk the influence of ca

The purpose of this research was to synthesize new regular poly(ester amide)s (PEAs) consisting of nontoxic building blocks like hydrophobic ␣-amino acids, ␣,-diols, and aliphatic dicarboxylic acids, and to examine the effects of the structure of these building block components on some physico-chemi

## Abstract Two new sequential poly(ester amide)s (PEAs) derived from 1,4‐butanediol, sebacic acid, and L‐alanine (PABA8) or glycine (PGBG8) are prepared and characterized. For comparative purposes the related polyesters (PEs) 4,10 and 6,10 are also studied. The calorimetric analysis shows that the
