Reaction Conditions

Reaction Steps

A 20% solids copolymer of acrylamide-DADM of molecular weight of 180,000 is prepared by polymerization of 75 wt % of acrylamide and 25 wt % of DADM. 50 parts of the copolymer is diluted with 150 parts of water in the reaction flask. 150 Parts of n-heptane are added and the mixture is stirred and cooled externally to 0° C. 1598 c.c. of chlorine are charged into the reaction mixture in 15 minutes while the temperature of the reaction mixture is kept at 0° C. to 2° C. during the chlorination process by external cooling. The reaction mixture is then poured slowly into 2 liters of ethanol with agitation. The product polymer is precipitated. The precipitate is collected by filtration and dried. It is found by analysis that the product polymer contains 26.2 mole % of N-chloroamide units.
