Abstract
Synthetic metal phthalocyanine sheet polymer of copper showed exceptional thermal stability with maximum polymer decomposition temperature (PDT max) 525 °C in air and 760 °C in nitrogen with char yield 91% at 800 °C in nitrogen atmosphere. Because of its excellent thermal stability, MS and GC–MS studies found to be very difficult. The present work deals with GC–MS studies on this copper phthalocyanine sheet polymer at various temperatures in the range 500–1000 °C. Tentative mechanisms for its modes of fragmentation are proposed and most probable degradation products are identified based on GC–MS studies.
