The mesophase behaviours of mixed solvent cellulosic liquid crystal systems, ethylcellulose/acrylic acid+water (EC/AA+W), ethylcellulose/acrylic acid+glacial acetic acid (EC/AA+GAA) and of ethylcellulose/acrylic acid systems blended with a flexible polymer, polyacrylamide (PAM+EC/AA), have been studied. The critical concentrations decreased in all the systems compared with the pure EC/AA system and the morphologies were affected, but still cholesteric. The cholesteric properties varied with composition of solvent and polymers. ©1997 SCI
