## Abstract Polyurethanes containing __z__βlysine segments in the main chain (PULL) were synthesized from 4,4β²βdiphenylmethyl diisocyanate, poly(tetramethylene glycol), and __z__βlysine oligomer as a chain extender. PULL film was treated with a 10% HBrβacetic acid solution and subsequently with a s

β¦ Synopsis
X-ray studies on polyurethanes containing arabinose-based polyurethanes the phase sugar derivatives in the main chain were separation is defined least of all. Glucoseperformed. I t was demonstrated that the and dulcitol-based polymers are intermemicrophase separation of rigid and flexible diates as to their supermolecular organizafragments was dependent on the nature of tion. Supermolecular organization models sugar derivatives. The supermolecular or-for block copolyurethanes under investiganization in disaccharide-based polymers gation were proposed.
