Conclusions

Mesomorphic films have been prepared from isotropic solutions of cellulose diacetate and triacetate in N-methylpyrrolidone by evaporating the solvents methylene chloride or methyl ethyl ketone. The films have high mechanical properties and are able to fibrillate as a result of realization of a liquid-crystalline state.

In heat stretching of the films up to 300%, structural rearrangements take place which are characterized by reorientation of rod-like structures in the direction of deformation. The finer anisometric elements located in such structures are oriented perpendicularly to the direction of stretch.
