ABSTRACT:
Polymeric electrolyte complexes are prepared by reacting at least one polymer represented by one of the following formulas: ##STR1## wherein R.sub.1 and R.sub.2 represent hydrogen or alkyl of 1 to 4 carbon atoms; R.sub.3 is --CH.sub.2 --C(R).dbd.CH.sub.2, --(CH.sub.2).sub.m COOC(R).dbd.CH.sub.2,--CH.sub.2).sub.m COOCH.sub.2 --C(R).dbd.CH.sub.2, or --CH.sub.2).sub.m O-C(R).dbd.CH.sub.2,--CH.sub.2).sub.m O-CH.sub.2 -C(R).dbd.CH.sub.2 or ##STR2## wherein R is hydrogen or methyl, m is a number from 1 to 3 and n is 0 or 1; at least one of R.sub.4, R.sub.5 and R.sub.6 is --CH.sub.2 --C(R).dbd.CH.sub.2, --CH.sub.2).sub.m COOC(R).dbd.CH.sub.2, --CH.sub.2).sub.m COOCH.sub.2 OC(R).dbd.CH.sub.2,--CH.sub.2).sub.m O--C(R).dbd.CH.sub.2,--CH.sub.2).sub.m O--CH.sub.2 --C(R).dbd.CH.sub.2, --CH.sub.2).sub.m CONH-C(R).dbd.CH.sub.2 or ##STR3## wherein R is hydrogen or methyl, m is a number from 1 to 3 and n is 0 or 1; the remaining R.sub.4, R.sub.5 and R.sub.6 groups represent alkyl or alkylol groups of 1 to 4 carbon atoms; b is an integer of 10 to 20,000; a/b is in a range of 0.01 to 2; c/b is in a range of 0 to 3; X is halogen or hydroxyl, and M is a vinyl monomer and/or a monomer having an ethylenic double bond, with a highly electrolytic polyanion dissolved in water or a mixed solvent of water and at least one member selected from the group consisting of water-miscible acids and organic solvents.
