Abstract
We performed viscosity measurements, at T = 50 degrees C, on poly(ethylene oxide) (H-(O-CH2-CH2)(n)-OH) at different molecular weight, dissolved in et hylene glycol (H-(O-CH2-CH2)-OH) and in one of its homologous systems, name ly ethylene glycol dimethyl ether (CH3-(O-CH2-CH2)-OCH3). The goal is to in vestigate the effects of the monomer end groups on solute-solvent interacti ons and, on this basis, to check the quality of these two solvents by using the Mark-Houwink-Sakurada scaling law.
