## Abstract The unperturbed molecular dimensions of poly(ethylene glycol) (PEG) samples (of different molecular weights) have been evaluated in aqueous solutions from viscosity measurements at 25, 30, 35, and 40Β°C. The unperturbed dimension, __K__~ΞΈ~, has been determined from extrapolation methods,
Separation of phenol from dilute aqueous solution through polyurethane membranes by pervaporation was investigated. The effect of the methylene group length in poly(alkylene glycols) on permselectivity and solubility of phenol was studied. The poly(alkylene glycols) were obtained by polycondensation
