dispersible filler, hardener triethylenetetramine, heat resistance, oligomer DER-331.


Polymer materials with high temperature resistance have been developed to repair the equipment of the gas production
complex. For their formation, epoxy dian oligomer DER-331, hardener triethylenetetramine TETA and multi-functional filler
oxytetracycline with a dispersion of 5–10 μm at a content of q = 0.50–2.50 pts.wt. (per 100 pts.wt. of epoxy oligomer DER-331)
were used. The thermal transformations of the developed polymers were studied by thermogravimetric analysis method (TGA)
using the derivatograph Thermoscan-2. It is shown, that polymer materials containing the filler oxytetracycline (C22H24N2O9) at q = 1.00–1.50 pts.wt. are characterized by the following parameters: the maximum of the initial mass loss temperature
T0 = 608.9–609.5 K, the final mass loss temperature Tfinal = 740.0–743.9 K, relative mass loss εrel = 66.7–67.3. Complex
assessment of thermal parameters using TGA-curves allows to ascertain the possibility of their use for the formation of coatings or adhesive materials up to a temperature of 609.5 K without changing their properties.
