Özet

Direct pyrolysis mass spectrometry is applied to investigate the thermal behavior of poly(2-isopropyl-2-oxazoline) (PIPOX, a thermoresponsive polymer) and poly[2-(3-butenyl)-2-oxazoline] (PBOX, a "clickable" polymer). It is found that the thermal degradation of PIPOX is started by a loss of side chains. At slightly higher temperatures the degradation of the polymer backbone occurs by random chain scission processes. In the case of PBOX, vinyl polymerization of the side chains produces chains with variable thermal stabilities. The number of repeating units of the polymer has almost no effect on the thermal behavior of PIPOX, but significantly affects both thermal stability and degradation product distribution of PBOX. © 2012 WILEY-VCH Verlag GmbH & Co.
