IR- and NMR-spectroscopy

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.

New hydroxy-derived resin with primary hydroxy and epoxy groups has been synthesized on the basis of ED-20 epoxy resin and PolyTHF-2000 oligoether. The structures of the synthesized derivative and the product based on ED-20 epoxy resin and 1,4-butanediol which was synthesized by us earlier have been confirmed by IR- and NMR spectroscopy. The synthesized derivatives were investigated as polymeric components for bitumen-polymeric blends.

Using IR-and NMR-spectroscopy (1H and 13C) the structure of functional oligomers based on novolac phenol-formaldehyde and polyglycidyl phenol-formaldehyde oligomers has been characterized. The structure of modified phenol-formaldehyde oligomers has been confirmed by the presence of absorption bands and proton shifts corresponding to furan ring, methacrylic fragment, peroxy, hydroxyl, and phenol groups.
