This article describes the rheological properties of certain poly(ethylene oxide)s dissolved in water-based solvents. The experimental results show that the rheological properties in aqueous solutions are significantly affected by the solvent properties, which have been changed by the use of ethanol

## Abstract Diblock copolymers of ethylene oxide and DL‐lactide (E~m~L~n~ copolymers) were prepared by sequential anionic polymerisation and characterised by gel permeation chromatography (GPC) and ^13^C NMR. Their association and surface properties in aqueous solution were studied by surface tensi
Specific volumes of aqueous solutions of triblock (PEP) copolymers of ethylene oxide and propylene oxide at solute weight fractions 0.1 Q w2 Q 0.39 were measured in the temperature range from 5 to 65°C. Partial molar volumes r2 per chain repeat unit, their temperature quotient 8r2,1aT, and excess pa
