ABSTRACT:
Vinyl monomers are polymerized in high yield to water-soluble polymers or copolymers by free radical polymerization of an aqueous reaction mixture containing the vinyl monomer(s), an UV-activated photoinitiator and a heat-activated chemical initiator. The polymerization is initially carried out by exposing the monomer mixture to UV radiation to activate the photoinitiator and then is carried out under the influence of free radicals produced by the chemical initiator.
