Abstract

Acrylic homopolymers can be identified easily using Raman spectroscopy. However, for the copolymers (particularly styrenated acrylics) identification of the monomer structural components is difficult due to the complexity of the spectra. In an effort to overcome this problem use was made of the expert system, EXSPEC, developed at Utrecht University for the automated interpretation of vibrational spectra; the aim is to simulate the human interpretation process using rules. Interpretation rules were generated for homopolymer spectra and these were applied to mixture and copolymer spectra. The approach is proving successful for copolymers examined so far. The detection sensitivity for the rules have not been fully tested, however, components such as ethyl acrylate have been identified at the 9%w/w level in a copolymer.
