ABSTRACT:
Hydrophobic water-insoluble monomers, such as alkyl acrylamides, which are solid at room temperature may be sufficiently dissolved in concentrated acrylamide or methacrylamide monomer solutions, in the absence of cosolvents, to allow copolymerization to occur without substantial phase separation. The hydrophobic monomer is added to the acrylamide monomer solution and heated, with agitation, to above the melting point of the hydrophobic monomer. Thereafter the temperature must be maintained at no lower than about 15.degree. C. below the melting point.
