The purpose of this research is to study the conditions of thermal curing of unsaturated polyesters (NPEP) using IR spectra and thermal analysis. The curing of synthesized unsaturated polyesters based on the products of alcoholysis of secondary polyethylene terephthalate has been studied. The influence of the system of hardeners on the curing process is shown. Based on thermal analysis, it was shown that with an increase in the amount of accelerator from 0,3 to 0,5 wt. part of PN-MA-03 with NPEP grade shows a decrease in the gelation time from 13,5 to 12,0 minutes, the duration of self-heating of polyester from 27.5 to 25 minutes, and an increase in the exothermic temperature from 121 to 135 °C. The curing process of unsaturated polyester of the PN-MA-03 brand has been studied. It was revealed that in the temperature range of 80-140 °C deeper structuring occurs and the process of curing of NPEP proceeds due to the polymerization of vinyl (for styrene) and trans-allyl groups (for NPEP).
