Abstract

Some features of the: formation of liquid-crystal structures based on polymer complexes are discussed for composites of polyvinyl alcohol with cellulose esters, polyacids, inorganic acids and variable-valence metals. Rheological and optical methods of research as well as a dielectric relaxation method have revealed the formation of several types of interpolymer complexes in liquid flowable media. This leads to formation of associates and results in an increase of the molecular mobility of macromolecules and their fragments. The structure and properties of the complexes depend on the media compositions and on the method of additive introduction. The composites obtained -can be used for producing light-, electric- and heat-sensitive film materials and sensors of various types.
