✦ Synopsis


The synthesis of three new stereoregular AB-type polyamides based on Dribono-1,4-lactone, L-arabinose, and D-xylose has been carried out by the active ester polycondensation method. These polyamides were characterized by elemental analysis, IR and NMR spectroscopies, and powder X-ray diffraction. They displayed optical activity and had a pronounced affinity to water, although they were not soluble in this solvent. The polyamide obtained from D-ribono-1,4-lactone was highly crystalline and yielded films with spherulitic texture.

Stereoregular, enantiomerically pure, chiral polyamides of the -AB-type, containing a natural (glycine) and a synthetic [(S)-5-amino-4-methoxypentanoic acid (AMP)] component have been prepared by the active ester polycondensation method. Thus, polyamide 7 was obtained by polycondensation of the conv
