Abstract

The invention relates to mixtures of cationic benzene carboxylate polymers, a method for their preparation and use, which polymers are defined by the formula ##STR1## wherein R and R' are selected from the group consisting of alkyl or alkenyl having from 1 to 20 carbon atoms, aryl, ##STR2## with the proviso that at least one of R and R' is quaternized; Q is hydrogen, SO.sub.3 -alkali metal, SO.sub.3 H, COOH or COO-alkali metal, between about 55% and about 90% of Q in said mixture being hydrogen and between about 10% and about 45% of Q in said mixture being other than hydrogen; a and b each have a value of from 1 to 200, except that the sum of a+b is at least 25; X is hydrogen, lower alkyl or mixtures thereof in random or block distribution when a and/or b is greater than 3; c has a value of from 2 to 10,000; R.sub.1, R.sub.2 and R.sub.3 each contain from 1 to 22 carbon atoms and are alkyl, hydroxy alkyl or alkylamido lower alkyl; R.sub.5 is ##STR3## --OH, --OCOR.sub.1 or --OR.sub.1 ; R.sub.6 is hydrogen or --COR.sub.1 ; R.sub.7 is hydrogen, --(CH.sub.2).sub.m OCOR.sub.1, --(CH.sub.2).sub.m NH.sub.2, ##STR4## m has a value of from 0 to 3; A is a halide anion or sulfonate, sulfate or alkali metal and n has a value equal to the number of quaternized nitrogen atoms in the molecule.
