<p>A continuous process is provided for producing substantially homogeneous, non-tacky solid terpolymers of acrylamide, an alkali metal salt of acrylic acid and a hydroxyalkyl acrylate, and copolymers, optionally crosslinked, of a (meth)acrylamidoalkylsulfonic acid or alkali metal salt thereof and (meth)acrylamide or N-alkyl(meth)-acrylamide, by rapidly heating a single phase high solids aqueous solution of the monomers to polymerization initiation temperature immediately prior to depositing a uniform layer of the solution and polymerization initiator onto a moving surface having a surface temperature at the point of deposition which is substantially equal to the polymerization initiation temperature.</p> |
