Menzheres, M. Kligshtein, A. Degtyareva, V. Vatulev, V. Magdinets] The spectral effects were investigated in the transformations of the photoinitiator of the cationic polymerization of epoxide compounds, i.e., triphenylsulfonium hexafluorophosphate (TSHP), in the solid state (in a tablet with potassium bromide), in propylene oxide, and in its oligomer. Absorption bands sensitive to the phototransformations of the initiator were found. Since a high yield of the products from the photolysis of TSHP must be expected under the experimental conditions, it seemed of interest to study the substance precipitated during the photochemical polymerization of propylene oxide in the presence of the photoinitiator. Small differences were found between the IR spectra of the initial initiator and of the precipitate. The spectral effects accompanying irradiation of the precipitate the UV light are identical with those observed for the initial photoinitiator. The effectiveness of the precipitated substance as photoinitiator for the polymerization of propylene oxide and epoxide resin UP-650T is comparable with the photoinitiating activity of TSHP.
