摘要：

Low molecular weight oligomers of polystyrene and poly-TMDQ (2,2,4-trimethyl-1,2-dihydroquinoline) have been separated and identified by liquid chromatography and field desorption mass spectroscopy (LC-FDMS). The LC separation procedures utilized a C18 μBondapak (reverse phase) column with a methanol/tetrahydrofuran (polystyrene) or water/tetrahydrofuran (poly-TMDQ) gradient system. Eluted peaks were trapped individually for FD mass spectral identification. Oligomers containing up to 18 styrene monomer units and up to eight TMDQ units were identified. In addition a number of degradation products in poly-TMDQ were characterized. © 1979, American Chemical Society. All rights reserved.
