Amine‐derivatized poly(diallyldimethylammonium chloride) from N‐vinylformamide copolymerization

Abstract The reactivity ratios for the aqueous free‐radical copolymerization of diallyldimethylammonium chloride and N ‐vinylformamide were found to be 0.13 and 1.92, respectively, from a Fineman–Ross analysis of a series of batch polymerizations. Because batch polymerization could not give a uniform product in a high yield with two monomers of such different reactivities, a semibatch procedure was developed in which the more reactive N …
