| Abstract: | The two cyclic oligomers of polyaryletherketon e and two macrocylic oligo mers of aryl are studied by matrix-assisted laser desorption ionization-time o f flight mass spectrometry (MALDI-TOF-MS) and the distribution of oligomericio ns with differenent degree of polymerization is discussed, respectively.The expe rimental results sh ow that MALDI-TOF-MS technique is a direct, accurate and rapid tool for the an alyses of cyclic oligomers of polyaryletherketone and aryl macrocylic oligomers. |
