UV-INITIATED SOLIDIFICATION OF LIQUID-CRYSTALLINE ETHYLCELLULOSE/ACRYLIC ACID FILMS AND BANDS FORMED IN THIS PROCESS
Solidification of liquid crystalline ethylcellulose/acrylic acid films was realized by UV-initiated polymerization of the solvent acrylic acid. It has been found that the original textures were immobilized to a great extent, and a novel ''banded texture'' formed at the same time. The optical properties of this texture were different from the banded texture formed by shearing lyotropic or thermotropic polymer liquid crystals. Formation of such bands is assumed to be related to an uncompleted phase separation.
