Abstract
The present invention provides a process for improved incorporation of diallyldimethylammonium chloride (DADMAC) into an acrylamide polymer. This invention makes use of a copolymerizable promoter monomer. Also provided by the present invention are inverse emulsion terpolymers of diallyldimethylammonium chloride. The improved incorporation resides in the use of a promoter monomer that is more reactive with acrylamide than is the DADMAC monomer and is selected from ##STR1## wherein R is --H or CH.sub.3 ;
