Heat-resistant network copolymers based on rolivsans modified with aromatic diamines

Thermochemical transformations of rolivsans with aromatic diamines were studied by IR and NMR (1H, 13C) spectroscopy and by dynamic mechanical, thermal, and elemental analysis. The heat resistance of rolivsans is considerably enhanced by their modification with small additions (10 ± 5%) of an aromatic diamine with curing at 150–300 (320)°С.
