Abstract

• Densities, viscosities, and refractive indexes for binary systems contg. mixts. of poly(ethylene glycols) at the same no.-av. mol. mass (Mn » 300) but different polydispersities (mol. mass distribution between 1.15 and 1.98) with di-Me carbonate or di-Et carbonate were detd. at 313.15 K and at atm. pressure. The measurements were carried out over the whole range of compn., using a vibrating-tube d. meter, Ubbelohde viscometers with a Schott-Geraete AVS 310 unit, and an Abbe refractometer. Densities, viscosities, and refractive indexes were used to compute the excess vols., VE, viscosity deviations, ? ?, and deviations in molar refraction, ?R. Results were fitted to the Redlich-Kister polynomial, and the adjustable parameters were obtained using least-squares methods. The viscosity dependence on temp. was investigated between (309.15 and 327.15) K for some solns. in a restricted compn. range. A qual. discussion on these quantities in terms of mol. interactions is reported. (literal)
