HALOGEN-CONTAINING OLIGOSULFONES FOR POLYCONDENSATION Russian patent published in 2019 - IPC C07C315/04 C07C317/22 C08G75/23

Abstract RU 2702099 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, having high thermo-, heat-, fire-resistance, well soluble in chlorinated hydrocarbons and easily processed by watering from solution. Halogen-containing oligosulfones for polycondensation have the following formula, in which n = 1–10.

EFFECT: invention enables to obtain oligomers having high activity in reactions of acceptor-catalytic polycondensation, as well as broaden the range of oligomers with end phenol groups.
