The effects of silica, mullite, α‐alumina and γ on the nonoxidative thermal degradation of poly(vinyl butyral) are described. To varying degrees, all of the inorganic oxides catalyzed reactions that produced butanal. Other significant products included: water, butenal, acetic acid, and alkyl aromatics. Two distinct evolution steps were detected for samples containing mullite and α‐alumina, suggesting that multiple interactions existed between these oxides and the polymer. The relative amounts of volatile aromatic products evolved by heating polymer/oxide samples were greater than the amounts generated from the neat polymer. For the polymer/γ‐alumina sample, carboxylate species were detected on oxide surfaces above 250°C, indicating that a reaction between the polymer and γ‐alumina occurred. © 1996 John Wiley & Sons, Inc.
