摘要：

This paper presents a thermodynamic study of aqueous solutions of ethylene oxide-propylene oxide statistical copolymers. In a first step, copolymer samples are carefully characterized by elemental analysis, H-1 and C-13 nuclear magnetic resonance, gel chromatography and light scattering. Secondly, the lower critical solution temperature is studied as a function of copolymer composition and concentration. This phase separation behaviour as well as the temperature dependences of intrinsic viscosity, second virial coefficient, Flory interaction parameter chi and partial specific volume are discussed in the background of different polymer theories.
