OLIGOSULFONES FOR POLYCONDENSATION Russian patent published in 2019 - IPC C07C317/22 C07C41/30 C08G75/23

Abstract RU 2702104 C1

FIELD: chemistry.

SUBSTANCE: invention relates to high-molecular compounds, in particular to aromatic simple oligosulfones intended for production of polyester sulphones with high values of reduced viscosity and molecular weight, high thermal-, heat- and fire-resistance, well soluble in chlorinated hydrocarbons, easily processed by watering from solution. Oligosulphones for polycondensation have the formula given below, where n = 1–20.

EFFECT: invention enables to obtain oligomers which have high activity in reactions of acceptor-catalytic polycondensation and extend the range of oligomers with end phenol groups.
