Membranes of random and graft copolymers of fluoroalkyl acrylate (FAA) and methylstyrene (MSt) were prepared. Permselectivity for water-ethanol mixtures was studied by pervaporation. Pervaporation rate of the random copolymer membranes were correlated with their glass transition temperatures. Permselectivity for water was governed by diffusivity through the membrane, as shown by the effects of temperature and size of the penetrants on the pervaporation rate. On the other hand, ethanol was efficiently permeated for the graft copolymer membrane because of its water-repellent property of FAA. Effects of the structures of the copolymer membranes on the separation for water-ethanol mixtures were discussed.
