The thermal degradation in vacuum of polymers containing aromatic or heterocyclic rings linked by various groups has been studied by a weight loss method. The most stable of the polymers examined were those with CO, mixed SO 2 and O, orSO 2 linkages. The stability of these were superior to or comparable with poly‐ p ‐phenylene and poly‐ m ‐phenylene. The particular combinations of aromatic nuclei and linking groups used did not result in tractability as most of the polymers were insoluble and infusible, even though of low molecular weight. Substitution in the aromatic nuclei could improve tractability, though at the expense of thermal stability.
