Aqueous solutions of polypropylene oxide: unusual solution behaviour

Abstract

Density, calorimetric and rheological measurements for poly(propylene oxide)–water solutions, which are completely miscible over the total concentration range, indicate that, in dilute solutions of the polymer in water, interactions between the polymer and water are very similar to those seen with corresponding concentrations of short chain alcohols in water and also suggest that specific interactions between the polymer and water occur in dilute solutions of water in the polymer.
