Аннотация
The polymerization process of the dual cure resin cement AllCem (FGM, Joinvile, Brazil) was investigated theoretically and experimentally. The free radicals responsible for polymerization continuity were characterized by multi-frequency EPR spectroscopy (X-, Q- and W-band) and spectra simulation. It was observed by multifrequency electron paramagnetic resonance spectroscopy and spectra simulation that the paramagnetic species occur simultaneously and independently for both self-cure and photo-cure modes. The paramagnetic species generating the EPR signal are the same for both photo-cure and self-cure polymerization mechanisms.
