Pyrolysis mass spectrometry analyses of poly(3-methylthiophene)

Mass Spectrometry of Synthetic Polymers

“…The steps involved loss of the dopant followed by degradation of the polymer backbone. Similar results were found for BF 4 -doped, methyl-substituted polythiophene and for PF 6 -doped PTh (112,113). Athar et al used D-Py MS to characterize p-toluenesulfonatedoped polypyrole-thiophene-capped PMMA (114,115).…”

“…Pyrolysis combined with GC/MS continues to be an important tool for the characterization of polymers and polymer additives. As mentioned above, Curie point Py-GC/MS was used to study doped PTh polymers (111)(112)(113). Odermatt et al used Py-GC/ MS to quantify paper additives from three polymeric materials: a styrene acrylate copolymerizate latex, a urea formaldehyde resin, and a poly(vinyl acetate) (117).…”
