  • Publication number: 20200102414
    Abstract: A method of producing a polymerized product through an inverse emulsion polymerization reaction. The current method includes introducing an ultraviolet (UV) light sensitive initiator into an inverse emulsion monomer formulation comprising monomers and irradiating the monomer formulation with an UV light source. A polymerized product is formed from polymerization of the monomers in the presence of the irradiated UV light sensitive initiator.
