1. Field of the Invention
This invention relates to a novel polyion complex, that is, a polymeric electrolyte complex, and a process for preparing this polyion complex. More specifically, the invention relates to a process for preparing a novel polyion complex by complexing a polyanion with a polymer, as a polycation, having quaternary ammonium methylated hydroxystyrene units.
2. Description of the Prior Art
Conventional styrene-type polyion complexes can permit the introduction of only one quaternary ammonium methyl group at most on an average as a strong cationic group per unit of styrene, and when such a polyion complex is formed into a film, its ion density is low and the ionic bond power is insufficient. Accordingly, a film of good water permeability cannot be prepared from such a polyion complex. Conventional styrene-type polycations are expressed by the following formula ##SPC2##
Where R.sub.1, R.sub.2, R.sub.3, X, and n are the same as those defined with respect to the general formula (I) to be given later. PA0 wherein OH is para or meta to --CH--CH.sub.2 ; each of R.sub.1, R.sub.2 and R.sub.3 is an alkyl group, cycloalkyl group, alkenyl group, substituted or unsubstituted benzyl group, or any of these groups having introduced thereinto a hydroxyl group, or ##EQU1## forms a nitrogen-containing or oxygen-containing heterocyclic group, or represents a dialkanol amine or N-alkyl alkanol amine, or R.sub.3 is CH.sub.2 COOH, H, or O forming a coordination bond with N of the quaternary ammonium group; PA0 X is halogen or ROSO.sub.3 in which R is a lower alkyl group; PA0 p is greater than 0 but below 2, p' is at least 0 but below 2, and the sum of p and p' is greater than 0 but below 2; PA0 n is at least 3; (CM) represents a vinyl monomer; and l is any number including 0.
