✦ Synopsis

A gravimetric method WBS applied to determine the solubility of CO, in poly(viny1 cyclohexanecarboxylate) below 1 atm. The temperatures were v d e d from 5 to 85"C, above and below the glass transition temperature. The sorption isotherms were concave to the pressure axis below Tg and they were tentatively analyzed by the dual-mode sorption model. Above Tg, the isotherms were linear and described by the Henry's law. Below 75"C, the diffusion c d c i e n t s of CO, were also obtained from the half-time of the sorption process.
