hardener

A new type of epoxyamine composition containing a copper (II) metalorganic complex has been created. The mechanism for obtaining the complex is developed. The structure and properties of the modified materials have been explored and analyzed, as well the relationship between them has been determined. A copper (II) chelate complex has been obtained and applied as a hardener for epoxyamine compositions.  It has also been found that the complex mentioned reduces the flammability of materials during the structuring. 

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.

The reaction of chemical modification of ED-20 epoxy resin with isopropylbenzene hydroperoxide has been studied. The process duration effect on the reaction between resin and hydroperoxide has been determined. The possibility to use the synthesized product as a component in the process of epoxy-oligoesteric compositions crosslinking with application of hardeners various by their nature has been studied.
