Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry was used successfully to determine three kinds of bisphthalazinone phenyl ether aromatic polymers with 1,8,9-trihydroxyanthranene as matrix. The polymerization degree of the polymers were determined to be 1 to 17. The influence of deflection value used in MALDI-TOF MS method was discussed.
