Abstract
The copolymerization of water soluble monomers with water insoluble monomers can be effected by using a solution of a water soluble surfactant to solubilize the water insoluble monomer. The aqueous medium containing the surfactant and water insoluble monomer is therefore a homogeneous, isotropic, transparent dispersion, into which the water soluble monomer can be dissolved and, after addition of a suitable free radical initiator, can be copolymerized to give a reaction mixture which does not phase separate, or contain substantial amounts of particulates of insoluble monomer. The copolymers which may be isolated from the reaction mixture are good viscosifiers of water and brine.
