Abstract
Water miscible monomers such as acrylamide are polymerized in an aqueous phase in the presence of an initiator containing a borohydride such as sodium borohydride and an easily reduced metal ion such as cupric ion.
Claims17
A process for polymerizing water miscible monomers which process comprises (1) contacting an aqueous phase containing a water miscible monomer with an initiating amount of an initiator containing a metal borohydride and a metal ion that can be reduced by the borohydride and (2) subjecting the resulting aqueous phase to conditions of aqueous phase polymerization sufficient to polymerize the monomer to form a water-soluble polymer.
