| Abstract: | Fast ion bombardment mass spectrometry (FIBMS) was used to identify cyclic oligomers containing aromatic rings produced in polycondensation reactions of poly aryletherketone, polyarylethersulfone and two polyarylesters using glycerol, thio-glycerol and 3-nitrobenzyl alcohol (3-NBA) as matrixes, respectively. The existence of different size (n value) cyclic oiigomcrs and their distributions were determined. The results indicated that the FIBMS was a powerful and rapid analytical method for the cyclic oligomers. |
