ION-COUPLED HALIDE CONTAINING FIBRE BASED ON SULPHUR AND ALKALI METAL CONTAINING IMIDAZOLE Russian patent published in 2016 - IPC D01F6/94 D01F6/78 D03D15/00 

Abstract RU 2578690 C2

FIELD: chemistry.

SUBSTANCE: fibre is obtained from a polymer containing imidazole groups. The fibre additionally contains: i) halide anions present in an amount in the range of 0.05 to 20.1 wt %, based on the weight of the fibre; ii) sulphur, where the sulphur is present in the fibre in an amount in the range of 0.05 to 3 wt %, based on the weight of the fibre; and iii) an alkali metal ion, wherein the alkali metal ion is present in the fibre in an amount in the range of 0.05 to 2 wt %, based on the weight of the fibre.

EFFECT: producing the fibre having improved tensile strength.
