As a first step in the elucidation of the microstructure of styrene copolymers using ultraviolet spectroscopy, the data available in the literature has been reviewed and reevaluated. It is shown by using simple error propagation analysis that the abnormalities observed in the extinction coefficients of styrene copolymers can be easily attributed to the experimental error. No significant deviations from the linear absorption behavior can be observed at the specific wavelengths reported in the literature (254–269 nm). As a result of this work, a useful set of correlations for the estimation of the copolymer composition have been obtained. These correlations appear to be adequate for copolymers of different microstructure.
