Abstract:
The present work is devoted to the research of possibility of bicyclic bisureas fragments inclusion
in polyure-
thane polymer structure and, as a consequence, improvement of mechanical properties of known
polyurethane polymers. The most convenient from stereometric point of view linear monomers such as
adipic acid and hexamethylenediisocyanate were chosen for interaction with bicyclic
monomer, namely tetra-N-
methylolglycoluril. The optimal conditions of tetraol preparation were found and influence of
various factors on its efficiency was shown. Polyurethanes were synthesized by step-growth
polymerization, molar masses of
polymers synthesized were determined, and some physical& mechanical properties were studied.
