Abstract
The early stages of thermal degradation of poly(styrene sulfone)s were studied with polymers from the copolymerization of styrene (M) with sulfur dioxide (S). The experiments were carried out in the temperature range 190–200°C in the early conversion range of 0–0.4% in nitrogen. The activation energy of thermal degradation was found to be in the range 180–300 kJ mol −1. The activation energy decreased with an increase in the content of sulfur dioxide in the polymer and with an increase in the content of SMS triad sequences. The activation energies of thermal degradation of SMS and MMS sequences were calculated as 175 and 390 kJ mol −1, respectively. It was found that SMS triad monomer sequence is the most sensitive microstructure in thermal degradation of the poly(styrene sulfone)s.
