The sorption characteristics of water, methanol and ethanol vapours in cellulose acetate (CA) รlms were measured by microgravimetry. The sorption isotherms for water vapours in the CA รlm at di โ erent temperatures in the range 20ร40ยกC do not obey the Flory equation over the whole water activity rang
