The TG(DTG) and DTA of poly(p-xylylene) and poly(α,α,α′,α′-tetrafluoro-p-xylylene) are reported. The degradation was performed from ambient temperature to 900°C in both air and nitrogen. Both polymer
degrade faster in air than under nitrogen but the fluorinated polymer eventually decomposed at higher temperature in air than
in nitrogen atmosphere. The activation energies of the degradation processes is given.
