Abstract
In this paper various polycarbonates are studied using static secondary-ion mass spectrometry. From the measurements information about the chemical structure of the polymers can be extracted. Apart from the structure of the repeat unit, also the structure of the polymer end-group and the distribution of monomers in a copolymer has been determined. Furthermore, the presence of cyclic oligomeric compounds in various polycarbonates has been established. A main-chain scission mechanism for the interaction of the primary ion beam with the polymers has been proposed, and with this mechanism it was possible to explain the structures of the most characteristic ions observed in the different types of spectra.
