Abstract
Water-soluble polymers of diallyl dimethyl ammonium chloride can be prepared from monomer solution containing a large amount of an alkali metal halide salt. Additionally, a method is disclosed for making high quality monomer which involves purification of allyl chloride which is used to prepare the starting monomeric material, optimum temperature control during caustic addition, and partial distillation to remove harmful impurities.
