✦ Synopsis

The sorption of propane in poly(ethy1 methacrylate) was investigated above and below the polymer T ' and the dual-mode sorption model parameters were evaluated. The Langmuir capacity decreased as the temperature was raised to 2"' ' and the apparent Henry's law constant exhibited a discontinuity at T ' . The enthalpy of microvoid filling A HH is more exothermic than the enthalpy of dissolution at T < Tg by about 8 kJ/mol.

Vapor sorption data were obtained for the ethylbenzene-poly(ethy1 methacrylate) system at 120OC. Successive step-change sorption experiments carried out at two-film thicknesses indicate the presence of maxima in the sorption curves.

The behaviour of poly(ethyl methacrylate) in the system ethyl acetate (l)/iso-propanol (2) is studied; liquid 1 is a solvent for the polymer and liquid 2 is a precipitant. The techniques laser light scattering, differential refractometry and viscometry are used. Preferential adsorption of 2 over the
