Poly(styrene-co-sodium acrylate) has been synthesized by emulsion polymerization of styrene and sodium acrylate at a ratio of 9:1 with the water-soluble initiator potassium persulfate. The reaction is fast, conversions are high, and the evolution of particle size follows the conversion curve. The final latex is stable and contains spherical particles 70 nm in diameter. The presence of the copolymer is confirmed by several methods including FTIR, and the copolymer evolves from rich in sodium acrylate to rich in styrene as the reaction proceeds.
