Abstract

Novel water-soluble cationic polymers are obtd. by reacting epihalohydrin (I) with an alkylene-polyamine of formula R1R2N-R-NH2 (where R is 2-6C alkylene and R1 and R2 are 1-6C alkyl) in the mole ratio (I): (II) = 0.60 - 2.7 : 1, starting with 50-90% of the amt. of (I) to be polymerised and reacting until the reaction medium has a uniform viscosity, than progressively reacting the remaining (I) to form the polymer, polymsn. being at 60-120 degrees C. The polymers have good flocculating and coagulating props. attributed to their highly branched and cross-linked structures and are used for heating industrial and sewage waters.
