The permeability coefficients of O 2 , N 2 , and CO 2 gases at 25Β°C were examined for composite membranes that were prepared by filling poly(ethylene oxide)(PEO) with different molecular weights into a porous membrane. The permeability coefficients of O 2 , N 2 , and CO 2 were 2 Ο« 10 Οͺ10 -4 Ο« 10 Οͺ10
## Abstract A new type of composite membrane for pervaporation has been developed. These membranes were prepared by freeβradical copolymerization of acrylic acid with a macromolecular polyfunctional crosslinker (allylhydroxyethylcellulose) inside the porous polyethylene (PE) film. It was shown that
