“…The volatile products are analyzed by GC‐MS. HR PyGC‐MS has many advantages that make it suitable for the characterization of polymers and the investigation of their thermal degradation 8–11. Minimum sample preparation is required, and the technique can be applied even to complex copolymers and mixtures of formulated and treated products such as composite polymer materials, polymer blends, and chemically modified polymers.…”

The thermal decomposition behavior of six derivatives of maleated polyethylene was investigated by high‐resolution pyrolysis gas chromatography–mass spectrometry. The results revealed that substituents attached to maleated polyethylene as amides formed from secondary amines were significantly less stable than imides formed from primary amines. Morpholine amide and N‐methylaniline amide derivatives of maleated polyethylene underwent significant decomposition at 160 °C and substantial decomposition at 200 °C. In contrast, the imide derivatives of maleated polyethylene were stable for long periods of time at elevated temperatures. Following 2 min of heating, the first traces of decomposition were detected at 200 °C for the 2‐aminoanthrancene imide derivative, at 255 °C for the 2‐phenethylamine imide, and at 280 °C for the 9‐aminomethylphenanthrene imide. With the exception of the 9‐aminomethylphenanthrene imide, all other derivatives decomposed to form the corresponding amine as the single most significant volatile product. The most likely explanation for this result is that the polymer contained small amounts of succinamic acid that did not close to form the imide. We concluded that the imide was stable even to 315 °C and that the amine was lost from β‐carboxyamide groups present in the sample. In the 9‐aminomethylphenanthrene imide derivative, we observed no loss of amine. Instead, we observed an alternative fragmentation process yielding 9‐methyl phenanthrene. The dependence of the thermal stability of these various derivatives of maleated polyethylene has important implications for the design of reactive‐blending strategies for polyolefins with other functional polymers. © 2000 John Wiley & Sons, Inc.

Abstract. Detection limits of heteroatoms and carbon were improved by eliminating the make-up gas and sustaining a 350 kHz radio frequency plasma inside the end of a fused silica gas chromatography (GC) column (0.32 mm i d . ) for capillary GC with atomic emission detection. Due to the small internal diameter of the plasma cell, a stable plasma was maintained in only 1.5-3 mL min" of heliumused as the GC carrier gas. The optical system consisted of a single low resolution monochromator for the near-infrared region in order to develop a simple and low-cost system. For on-column detection of C, H, S, CI, Br, and I, the plasma was doped with traces of oxygen. The oxygen dopant served to suppress peak tailing and to maintain high selectivity and repeatability. Detection limits for C, H, S, C1, Br, and I ranged from 0.9 to 11.8 pg s-', and selectivities between 4x I d and 4 x I d were obtained. On-column F-selective detection required a plasma doped with a mixture of hydrogen and oxygen. The detection limit for F was 13.0 pg s-'; however, the selectivity was poor (10) due to the low resolution of the spectrometer.
