The efficiency of a new approach to structural-chemical modification of unsaturated thermosetting resins was demonstrated by the example of curing of rolivsans containing small additions (0.5–2.0 wt %) of aromatic tetracarboxylic dianhydrides and aromatic tetraamines. As shown by dynamic mechanical and thermal analysis, the heat resistance of the modified matrix of the cured rolivsan, which is mainly used as a heat-resistant polymer compound for electric insulation, increases from 280 to 340–375°С, and the rigidity parameters decrease by a factor of 3–6, which is of much practical interest.
