Molecular weight of ethyl cellulose by dielectric dispersion of solutions in solvents of low dielectric constants

Abstract

Abstract The critical frequencies for ethyl cellulose solutions were determined by a “differential” bridge method in carbon tetrachloride, benzene, and toluene. Correlations between the critical frequency and degree of polymerization were found to be similar to those previously reported. Intrinsic viscosity data for ethyl cellulose in four solvents of low dielectric constant are also included.
