Abstract:

The possibility of chemical interaction between 6-aminophenolenone dye and polyurethane on a formation stage of the latter has been shown by EPR, WAXS, and visible spectroscopy methods. The polymer matrix was synthesized by the prepolymer, obtained from hexamethylene diisocyanate and oligodiethyleneglycol adipate with molecular mass of 800. Trimethylolpropane has been used as hardener. In order to show chemical interaction between the dye and polyurethane the model reaction of 6-aminophenolenone with hexamethylene diisocyanate was carried out. Chemical interaction has been obviously determined by IR-spectroscopy. IR spectra analysis of the reaction product and initial components were carried out, as a result, a formation of diurea was found. The results obtained give prospects for its applications as efficient media in laser active elements.

Keywords: Polyurethane, 6-aminophenolenone dye, EPR, WAXS, visible- and IR-spectscopy.
