Abstract The pyrolysis of some perfluoroalkylene‐linked aromatic and heteroaromatic polymer precursors and a poly(1,3‐phenylenehexafluorotrimethylene) has been studied using a combined pyrolysis‐gas chromatographic‐mass spectrometric method. Whereas the electron‐impact induced fragmentations of the polymer precursors are almost exclusively controlled by cleavage β to the aromatic or heteroaromatic ring, thermolysis of these compounds yields products whose formation is consistent with the occurrence of primary cleavage processes that are not confined β to the ring.
