Abstract
High molecular weight poly(allyltrialkylammonium) salt flocculants are obtained by preparing a preliminary poly(N,N-dialkylacrylamide), reducing the preliminary polymer to form an intermediate poly(allyldialkylamine), and quaternizing the intermediate polymer to form the final polyquaternary salt.
