| Abstract: | Ethyl cyanoethyl cellulose (I) was soluble in many organic solvents and formed liquid- solns. above the crit. concentration With increasing concentration, the solution was transformed from isotropic to anisotropic state through a biphasic state. Phase separation was observed in I-dichloroacetic acid and I-trifluoroacetic acid biphasic solns. The liquid crystals could develop into a spherulitic structure. For organic acidic solvent systems, the crit. concentration decreased with increasing acidity. The crit. concentration decreased with decreasing polymer-solvent interaction parameter for most organic solvents. |
