Abstract
Abstract This invention relates to polymers of quaternary thiazines having the recurrent structure <IMAGE> WHERE Z is S, SO, SO2, x is 2 or more, R1 is a hydrocarbon or substituted hydrocarbon, R2 is alkylene, alkenylene, aralkylene, alkylene ether, X is an anion, n is a number from 3-500. These polymers are useful as flocculants and/or water clarifiers, corrosion inhibitors, antistatic agents, demulsifiers, microbiocides, algicides and the like.
