Abstract
AbstractSummary: Water‐soluble poly(2‐acrylamido‐2‐methylpropane‐1‐sulfonic acid‐co‐1‐vinylimidazole) (P(AMPS‐co‐1‐VIm)) and poly(2‐acrylamido‐2‐methylpropane‐1‐sulfonic acid‐co‐2‐(dimethylamino)ethyl methacrylate (P(AMPS‐co‐DAMA)) are studied as it is known that the copolymer composition is affected by pH of the monomer phase in inverse miniemulsion. The distribution of the basic monomers in the continuous and dispersed phase changes due to their degrees of protonation. The amounts of the monomers in the cyclohexane phase is determined by gas chromatography, the copolymer composition is studied by elemental and thermogravimetric analysis. An insight into the monomer distribution in the polymer is provided by simultaneous potentiometric and conductometric titration of polymer solutions.
