Abstract
Reactive oligomers with free epoxy and peroxy groups based on a cyanuric epoxy resin and tert-butylhydroperoxide (PDCER) have been synthesised in the presence of 18-Crown-6+ZnCl2 as a catalytic system. The effect of temperature and process time on the PDCER properties has been determined. The PDCER structure has been confirmed by chemical and IR-spectroscopic analyses. Using ED-20 commercial epoxy resin (70 mass parts), petroleum resin (5 mass parts), TGM-3 oligoesteracrylate (10 mass parts), PDCER (25 mass parts), and polyethyleneamine as a hardener, the stepwise cross-linking has been performed at room temperature for 24 h and then at 383, 403 or 423 K for 15, 30, 40 and 60 min. Three-dimensional films containing both epoxy and peroxy groups have been obtained.
