Abstract
Matrix-assisted laser desorption ionization-time of flight mass spectr ometry (MALDI-TOF MS) was used to identify cyclic(aryl ether ketone) o ligomers, using 2,5-dihydroxybenzoic acid as a matrix, and Na+ and Kas cationization agents, The existence of different ring-sized cyclic oligomers up to 9 and their distribution were determined and compared with GPC results, The results indicated that MALDI-TOF MS was a powerf ul and rapid analytical tool for the cyclic oligomers.
