Abstract
A procedure was developed for the quantitative determination of free monomers in a copolymer of methacrylic acid and butyl methacrylate used in the medical industry for manufacturing antiseptic bandaging materials. It was found that the concentrations of methacrylic acid in a number of samples were higher than the permissible values. The use of a combination of several chromatographic techniques (HPLC, TLC, and GLC) was proposed for the more adequate characterization of the samples. The capabilities and limitations of each particular chromatographic technique in the proposed determination procedure are discussed.
