A1 - Just, Ulrich T1 - Matrix-assisted laser desorption/ionization mass spectrometry of synthetic polymers - Analysis of poly (ethylene oxides) N2 - Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) is a useful new technique for the determination of the chemical structure and the molar mass distribution of poly(ethylene oxides). Investigating different alkyloxy and aryloxy polyethylene oxides, we have shown that MALDI-MS gives accurate molar masses, provided that the oligomer masses are above 400 g/mol. Below 400 g/mol, mass discrimination effects have to be taken into account. A perfect fit of MALDI-MS with data, determined independently by supercritical fluid chromatography and high performance liquid chromatography, was obtained.
