Abstract: The content of residual monomers in styrene—acrylic acid copolymers of low relative molecular mass was quantitatively determined. These copo­lymers were produced by high-temperature (200 to 300 °C) continuous bulk copolymerization. Gas chromatography yielded the styrene content in the product, while liquid chromatography yielded the acrylic acid content. Problems associated with the analyses are discussed, as well as the influence of process variables such as temperature, residence time, monomer feed composition on conversion of the monomers. In addition an influence of the reaction conditions on the copolymer molecular mass and chemical com­position is evaluated.
