Abstract
The present invention provides a process for polymerizing diallyldialkyl ammonium compounds to produce polymers with increased molecular weight in which the polymerization is carried out in an aqueous medium containing an inorganic salt and a water soluble free radical initiator that does not react with the inorganic salt or a counterion of the diallyldialkyl ammonium compound to form a chain transfer or chain terminating agent.
