Akhranovych O. Polyurethanes with sulphonylhydrazide and crown-ether fragments in the main chain

The dissertation is devoted to the problems of synthessis and investigations of the new polyurethanes. For the first time the hydrazides of the sulphonyl derivatives of the monobenso-15(18)-crown-5(6) and di-benso-18-crown-6 and polyurethanes were synthesized. It is established that structure of macrochain have the influence on the properties of the obtained polyurethanes. The introduction of hudrazides of the sylphonyl derivatives of the crown-ethers into the polymeric main chain gives to latter the ability to complexation with metal cations and biological activity. Undoubtedly, the results of these investigations are evidence about the perspectivity of application polyurethanes in the different branches of the national economy.
