Abstract

The method involves the isothermal gravimetric determination of the absorption of an organic vapour into a thin film of liquid polymer spread upon an inert particulate support. Results are presented for the absorption of benzene and cyclohexane at 25°C in poly (dimethylsiloxane), and the concentration variation of the interaction parameter determined is compared with that found by other workers. The determination of the partial molar enthalpy of mixing was also examined by studying the absorption of hexane in poly (dimethylsiloxane) over the temperature range of 25 to 35°C, and comparing the value obtained with published values.
