Disclosed is a process which comprises (a) reacting allyl bromide with diethyl amine in a molar ratio of at least about 1 mole of allyl bromide per about 1.15 moles of diethyl amine and in a molar ratio of no more than about 1 mole of allyl bromide per about 2 moles of diethyl amine, thereby generating allyl diethyl amine in a monomer reaction mixture; (b) subsequently filtering the monomer reaction mixture to remove impurities; (c) subsequently reacting the allyl diethyl amine with allyl bromide, thereby generating solid diallyl diethyl ammonium bromide; (d) subsequently isolating the solid diallyl diethyl ammonium bromide; (e) subsequently dissolving the diallyl diethyl ammonium bromide in a solvent and adding thereto a polymerization initiator to form a polymerization reaction mixture; (f) subsequently heating the polymerization reaction mixture in a vessel equipped with a reflux condenser to a temperature of from about 90 to about 100° C., thereby generating poly(diallyl diethyl ammonium bromide); and (g) subsequently optionally isolating the poly(diallyl diethyl ammonium bromide) from the polymerization reaction mixture.
