A process for the production of water-soluble polyamine polymers by condensation reaction from ethylene dichloride and ammonia under pressure of 4-10 atmospheres which is conducted in two stages: 1. reacting ethylene dichloride and ammonia at a temperature of about 110.degree.-120.degree. C and at a pH of 9.0-10.0 for 1-3 hours in the presence of a first amount of alkali metal hydroxide to produce a polyamine reaction mixture; and 2. thereafter adding to said polyamine reaction mixture a second equal amount of alkali metal hydroxide wherein the total of the first and second amounts is equivalent to about 150% based on the equivalent weight of the available chlorine present and continuing heating the reaction mixture for about 8-12 hours at about 102.degree.-112.degree. C to produce a polyamine condensate polymer product of increased linear characteristics and thereafter quaternizing the product with methyl chloride.
