Abstract:
Polyquaternary polymeric flocculants, containing a substantially reduced total residual amount of epihalohydrin and 1,3-dihalo-2-propanol and less than about 1000 ppm of dialkylamine, are produced by reacting a polyquaternary polymer prepared from epihalohydrin, dialkylamine, and optionally a polyfunctional amine with a compound of the formula: ##STR1## wherein R. sub. 1, R. sub. 2, R. sub. 3 and R. sub. 4 are alkyl (C. sub. 1 -C. sub. 3), and R. sub. 5 is hydrogen or hydroxyl.
