Abstract: This invention provides a process for preparing novel hydrophobically associating polymers containing cationic functionality which are useful for clean-up of waste waters containing organic contaminants. These water soluble polymers contain both water soluble and water insoluble monomers. The water soluble monomers are acrylamide (AM) and a salt of an unsaturated amine base (C), and the water insoluble monomer is a higher alkyl(meth)acrylamide or alkyl(meth)acrylate (R). These polymers are referred to as CRAM. The process relies on the dissolution of the water insoluble monomer(s) into an aqueous solution of water soluble monomers by means of a water miscible mutual cosolvent.
