Abstract
Novel polymerizable cationic monomers, which contain two or more cationic groups in the molecule, and homopolymers and copolymers thereof are described. These novel cationic monomers are compounds represented by the general formula: ##STR1## AND THE QUATERNIZED DERIVATIVES THEREOF (IN WHICH THE TERMINAL TERTIARY AMINO GROUP HAS BEEN QUATERNIZED TO A QUATERNARY AMMONIUM GROUP) OF THE FORMULA: ##STR2## In the forgoing Formulas 1 and 2: A, each of which may be the same or different, represents an alkylene group of from 1 to about 20 carbon atoms but including oxygen interrupted alkylene groups (i.e.; a polyglycol ether group of the formula ##STR3## WHEREIN R.sup.5 represents H, methyl or ethyl and x represents an integer of from 1 to about 20); PA1 R represents H or methyl; PA1 R.sup.1 represents H or, when R is H, an alkyl group of 1 to 4 carbon atoms, R.sup.1 preferably H or methyl; PA1 R.sup.2, r.sup.3 and R.sup.4, each of which may be the same or different, each represents alkyl of from 1 to about 20 carbon atoms, aryl (preferably phenyl), alkaryl (preferably benzyl) or the R.sup.2 and R.sup.3, on the same nitrogen atom, taken together may represent a divalent aliphatic group of 4…
