MALDI-TOF MS and sizeexclusion chromatography were chosen and indirectly coupled to identify and quantify the different species. While, as expected, the isocyanate trimer and pentamer are the two main components, homologues until the tridecamer could be identified with MS. Moreover, the isocyanurate cycle occurs preferentially on the primary isocyanate group. According to the calculated composition, a numberaverage molecular weight of 775 and a number-average isocyanate functionality of 3,24 were determined. © 2013 by Walter de Gruyter GmbH & Co.
