Characteristics of the liquid crystalline state of cellulose derivatives

The effect of external factors on the structure of semi-stiff-chain polymers of the cellulose derivatives class is discussed. New methods of investigation are reported, where uniaxial flow of the polymer with constant stresses and temperature and mechanical orientation of the ferromagnetic filler along the lines of force of a homogeneous magnetic field during formation of chain structures were used as the external effects. The results of an analysis with optical methods indicate the ability of the polymers investigated to form a more ordered type of mesophase in the given conditions than is characteristic of them.
