ABSTRACT:
Cationic solution addition copolymers of monoethylenically unsaturated copolymerizable monomers are described having Mannich base side chains with the structure: ##STR1## where R and R' are selected from C.sub.1 -C.sub.8 alkyl and C.sub.1 -C.sub.8 alkanol, or are together constituted by a C.sub.2 -C.sub.8 alkylene group. This copolymer is preferably reacted with a diepoxide in a stoichiometric deficiency with respect to the amine groups in the side chains. At least a portion of the tertiary amine groups are then reacted with a solubilizing acid to form a salt which enables the copolymer to be dissolved in water.
