| Abstract: | By means of the method of refractometry, we studied the lyotropic liquid crystal of cyanoet-hyl cellulose in dimethylforamide (DMF) and dimethyl sulfoxide (DMSO) and measured the critical concentrations of phase transition C1 and Ca. A series of refractive index-concentration plots were obtained and discussed. It was shown that refractometry was an effective method to research polymer liquid crystalline olutions. |
