摘要
This paper describes the automated generation of interpretation rules for the characterization of aromatic polymers. Peak tables obtained from diffuse reflectance and attenuated total reflectance spectra are used to generate these rules. In order to improve the information content of the peak tables the role of second-order derivative spectra is investigated. Spectral windows, characteristic for a particular fragment, tend to become less specific due to an increase in the number of peaks. Application of interpretation rules obtained from homopolymers to spectra of copolymers and blends yields satisfactory results. Further improvement in the rule generation process is achieved by using mixture spectra.
