Abstract
The polymer poly(Me methacrylate) (PMMA) was analyzed using the matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) technique. The MALDI-TOF MS app. was coupled with a collision-induced dissocn. (CID) unit. The performance of the MALDI-TOF/TOF MS method in polymer anal. was demonstrated using a PMMA calibration std. The CID unit allowed the fragmentation of single peaks from the MALDI-TOF/TOF MS spectrum. The distributions obsd. in the 2nd level mass spectra depend on the end groups of the PMMA macromol. and on the fragmentation process. The MALDI-TOF MS/MS technique is suitable to det. the mol. compn., the end groups, and the sequence of a macromol. as well as the reaction mechanisms of polymn. reactions. [on SciFinder (R)]
