Abstract:<\/p>\n

On the basis of ionomer oligourethane prepared using polyoxytetramethylene glycol MM1000, 1,6-hexamethylene diisocyanate, 2,2-dimethylolpropionic acid and natural renewable components: xanthan (Xa) and castor oil (CO), according to the environmentally friendly technologies, the new stable polyurethane ionomer (IPU) dispersions and based biodegradable under the influence of environmental factors (the model conditions) film materials have been obtained. The rate of biodegradation of the IPUs, containing 5\u201334 % of renewable component, is in 4\u201323 times higher in comparison with matrix. The presence of renewable natural compounds reduces the cost of IPU. The biodegradability at the end of exploitation period contributes to the nature protection. The structure and supramolecular interactions in IPUs have been studied by IR spectroscopy and wide angle X-ray scattering (WAXS). WAXS studies have shown that IPU \/ CO<\/em>17<\/em>\u00a0has an amorphous structure and is the subject to the lowest degradation while the amorphous-crystal Xa-containing IPUs possess high degradability. Small-angle X-ray scattering has confirms the heterogeneous structure of IPU \/ CO<\/em>17<\/em>\u00a0and IPU\/ CO<\/em>14<\/em>Xa<\/em>20<\/em>\u00a0at the nanolevel <\/em><\/p>\n
