Semi-interpenetrating polymer network membranes based on sulfonated polyimide-siloxane and epoxy polymers have been prepared [61]. The membranes show desirable mechanical properties and thermal stabilities, with proton conductivities superior to those of Nation 117 at 80 °C. [Pg.351]

A number of liquid crystalline polyphosphazenes with mesogenic side groups have been prepared (48—50). Polymers with nonlinear optical activity have also been reported (51). Polyphosphazene membranes have been examined for gas, liquid, and metal ion separation, and for filtration (52—54). There is interest in phosphazene—organic copolymers, blends, and interpenetrating polymer networks (IPNs) (55—61) to take advantage of some of the special characteristics of phosphazenes such as flame retardance and low temperature flexibility. A large number of organic polymers with cydophosphazene substituents have been made (62). [Pg.258]

Our research with the SLMs has centered on the synthesis of highly stable membranes for long term metal ion transport. Since it is advantageous to maintain polypropylene as the basic support structure due to its commercial availability, a versatile membrane modification technique has been found to be that involving interpenetrating polymer networks [IPNs]...

Lee et al. (1990) studied the PV of EtOH-water mixtures by cationic-anionic interpenetrating polymer network (IPN) membranes. The cationic PU prepared by quaternizing the tertiary amine from A -methyldiethanolamine and the anionic acrylic copolymer from acrylic acid were used as the cationic and anionic components. The separation factor increased as the content of the anionic component in the membrane increased. The ion content in the membrane was also found to be an important factor for the optimum permseparation of water. Better performance was achieved by PEG-based PU as the cationic component of the IPN membrane. The highest selectivity was observed for the IPN membrane with 10 wt% of PEG-based PU. [Pg.276]
