    • The films were prepared by radical polymerization of a mixture of I, III and IV using 1,2 ethanedioldimethacrylate and AIBN (2.0 wt%) as initiator. The nominal cross-linking ratio, i.e., the ratio of the number of moles of monomers to the cross-linking agent, wasyl 00:1, and the film thickness was y110 mm. The addition of a cross-linking agent is necessary in order to obtain membranes with adequate mechanical properties. The reaction was carried out in a silanized glass mold of 100 mm thickness in an oxygen-free atmosphere at 65 uC for 5 h
