ABSTRACT:
Quaternary dialkylaminomethyl polymers derived from (alk)acrylamide and about 1 to about 15 mole percent ethylenically unsaturated anionic comonomer wherein the resulting ampholytic polymer has a standard viscosity of at least about 2.1 cps are disclosed. Processes for the preparation of these polymers and their use in flocculating suspended material in paper deinking sludges and deinking process waters are also disclosed.
