Epoxy Composites Filled with Natural Calcium Carbonate. 3. Epoxy Composites Obtained in the Presence of Monocarboxylic Derivative of Epidian-6 Epoxy Resin
A monocarboxylic derivative of Epidian-6 with free epoxy and carboxylic end groups (MCDER) has been synthesized using Epidian-6 epoxy resin and sebacic acid. The structure of MCDER was confirmed by a spectral analysis. The thermal stability of MCDER has been established and the formation of cross-linked films based on epoxy-oligomeric mixtures consisting of Epidian-5, TGM-3 oligoesteracrylate, and polyethylene polyamine has been studied in its presence. By means of IR spectroscopy, the chemistry of the mixtures formation has been established.
