i.r. Spectra of poly(dimethyl-p-silphenylene), poly(tetramethyl-p-silphenylene-siloxane) and their pyrolysis residue were investigated and gas chromatographic analyses of the volatile pyrolysis products were performed. Scission of the polymer chain results in radicals, leading to some volatile products and also to cross-linking. It represents the main thermal degradation reaction in both polymers. A rearrangement of the siloxane bonds, altering the polydispersity and producing a small amount of some cyclic volatile products, may also take place in poly(tetramethyl-p-silphenylene-siloxane).
