Notes:
X-ray studies on polyurethanes containing sugar derivatives in the main chain were performed. It was demonstrated that the microphase separation of rigid and flexible fragments was dependent on the nature of sugar derivatives. The supermolecular organization in disaccharide-based polymers is the most ordered one. In xylose- and arabinose-based polyurethanes the phase separation is defined least of all. Glucose- and dulcitol-based polymers are intermediates as to their supermolecular organization. Supermolecular organization models for block copolyurethanes under investigation were proposed.
