**Abstract**
 In order to determine the stability of crosslinked phenolic resins, their thermal degradation was studied in controlled atmospheres, both inert and oxidising. The structures of gaseous products released and of the degradation residues indicated that they depend on the degradation atmosphere, temperature, and the conditions in which the crosslinked resins were prepared. In the case of thermal degradation in an inert atmosphere, cyclic compounds and low molecular weight compounds were formed. In the case of degradation in an oxidising atmosphere, cyclic compounds are negligible, while large quantities of low molecular weight compounds are released. Formaldehyde is released in both atmospheres, with less released by resins prepared with cycle 2. The analysis of degradation residues is claimed to prove that such resins exhibit thermal stability up to 300 degrees C in an oxidising atmosphere, and up to 380 degrees C in an inert atmosphere. 20 refs.
