POLYMER COMPOSITION AND METHOD OF PRODUCING A SPINNING SOLUTION BASED ON A POLYMER COMPOSITION Russian patent published in 2020 - IPC D01F6/96 D01F1/10 C08K3/04 C08K5/34 B82B3/00 

FIELD: technological processes.

SUBSTANCE: invention relates to polymer compositions used for making fibrous materials. Polymer composition contains a metal-containing phthalocyanine additive which is copper hexadecagalogenophthalocyanine in amount of 14.998–4.999 pts.wt. As a polymer, the composition contains a product of copolycondensation of a mixture of terephthalic, isophthalic, paratoluilic, metatoluilic acid and hydrazine sulphate, and metaazobenzenedicarboxylic acid in amount of 85–95 pts.wt. Additive additionally contains carbon nanoparticles in amount of 0.002–0.001 pts.wt. Invention also relates to a method of producing a spinning solution based on said polymer composition.

EFFECT: ensuring preservation of rate of molding, dynamic viscosity and concentration of spinning solution with simultaneous formation of surface layer from carbon nanoparticles on produced filaments when passing through spinneret for molding of synthetic papers with electrostatic properties.
