Cross-linking of epoxy oligomeric mixtures consisting of industrial epoxy resin ED-20, oligoetheracrylate TGM-3, peroxide derivative of epoxy resin ED-24 and phenol-formaldehyde oligomer with unsaturated methacrylate fragments or peroxide groups was studied in the presence of polyethylenepolyamine at room temperature and heated to 383, 403 or 423 K for 15, 30, 45, 60 and 75 minute. The influence of mixture composition, temperature and cross-linking time on the content of gel fraction in the samples and the hardness of the polymer film was established. Using IR spectroscopy the formation of spatial structures of cross-linked epoxy oligomeric mixtures was confirmed.
