摘要：

The assumption on which both the structural analysis of polymers and the sequential analysis of co-polymers by fast-atom bombardment mass spectrometry (FAB-MS) is based, is that the ions detected in the FAB spectra do originate from species already present in the polymeric samples, and that the bombardment by fast atoms does not produce the fragmentation of macromolecules. FAB spectra do not yield direct structural information on large macromolecules, but such information can be deduced from the structural analysis of relatively low molecular weight species. Therefore, in a series of recent studies, FAB-MS has been used to identify the oligomers formed in the partial degradation of several co-polymers, and the results obtained have yielded detalied information on the microstructure of the materials investigated.
