На кривых зависимости вязкости от скорости сдвигаобнаружено появление квазиньютоновского участка в интервале от 20 до 40 c-1, обусловленное ориентационным упорядочением макромолекул в потоке. Для всех исследованных растворов обнаружено индуцированное сдвигом двулучепреломление, которое сохраняется в пленках, сформованных из водных растворов целлюлозы и ее смесей с хитозаном в ортофосфорной кислоте.</p></abstract><trans-abstract xml:lang="en"><p>Pseudoplastic flow behavior for solutions of cellulose (7%) and its mixture with chitosan (7,7-9,1 %) in aqueous orthophosphoric acid has been established under equilibrium steady shear flow conditions. The appearance of the quasi-Newtonian area from 20 to 40 s-1 has been observed in the curves of viscosity versus shear rate caused by orientational ordering of the macromolecules in the flow. For all the solutions shear induced birefringence has been observed. The films cast from these solutions in salt precipitation bath exhibit the birefringent texture.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гончар А.
