Cross linking and thermal destruction processes in thin films formed from dilute solutions of a copolymer of trifluorochloroethylene and vinylidene fluoride

Thermal desorption mass spectrometry has been used to investigate the mechanisms for thermal destruction of films prepared from dilute solutions of a copolymer of trifluorochloroethylene and vinylidene fluoride. It is shown that compared with films obtained from concentrated solutions, the ratio of the intensities of the low-and high-temperature stages of HCl and HF release changes substantially in this case. It is concluded that the low-temperature stage of hydrogen halide release is attributable to cross-linking processes rather than to intramolecular reactions caused by the formation of double bonds in the chain.
