“…Degradation occurs at the SiPh bonds. A TG study of six cyclophane bis (sulfoxides) (XVII) showed that thermal decomposition occurs in two stages with stepwise loss of the sulfoxide groups at well-defined decomposition temperatures (140). The effect of energetic additives such as NH4C104 and others on the thermal stability of polyacetals, aliphatic and aromatic polyesters, and polyamides was investigated by isothermal and dynamic TG in nitrogen and air atmospheres (344).…”
