Mesophasogenic solvents in the vapor state actively affect the structure of cellulose acetates of different morphological forms (fibre, film, bulk polymer). On the supramolecular level, this is manifested by initiation of orientation processes and on the conformational level by a change in the optical density, up to a change in the direction of rotation of the cholesteric helix to the opposite direction. The approach found creates conditions for formation of a given structure and three-dimensional organization of the polymer matrix for manufacture of materials with improved properties and new qualities.
