ABSTRACT:
The copolymerization of water soluble monomers with water insoluble monomers can be effected by dissolving the water insoluble monomer into a homogeneous mixture of oil, surfactant, and cosurfactant and then diluting this with water containing the water soluble monomer to yield a predominently aqueous, homogeneous, transparent dispersion of microemulsion droplets. The polymerization is initiated with water soluble free radical initiators to give copolymers that are free of visible particulates and such that the reaction product remains homogenous. The components are chosen to yield copolymers that are water soluble and which viscosify at low concentrations.
