Abstract
PVT properties were measured for mixtures of poly(ethylene glycol methyl et her)-350 + anisole and poly(ethylene glycol)-200 + anisole at temperatures from 298 K to 338 K and pressures up to 50 MPa. Excess volumes are positive for these two polymer solution systems. The isothermal compressibilities w ere calculated with the aid of the Tait equation, which represented accurat ely the pressure effect on the liquid densities over the entire pressure ra nge. The experimental specific volumes were correlated with the Flory-Orwol l-Vrij and the Schotte equations of state.
