Abstract
Pyrograms of poly(2,6-dimethyl-1,4-phenylene ether) (PPE) samples were obtained by on-line high resolution pyrolysis-gas chromatography (HR-Pyg.c.). Characteristic peaks on the pyrograms (up to trimers) were assigned by using gas chromatography-mass spectrometry (g.c.-m.s.) and retention time data. The analysis of a series of fractions of varying molecular weight from a given PPE sample suggested that HR-Pyg.c. would be a powerful technique for characterization of the end groups of PPE when 13C-n.m.r. was used to take reference data for these end groups.
