POLYAMIDE COMPOSITION TO MANUFACTURE MOULDED PRODUCTS WITH IMPROVED SURFACE QUALITY AND METHOD OF ITS PRODUCTION (ITS VERSIONS) Russian patent published in 2017 - IPC C08L77/00 C08K3/04 C08K7/24 C08K9/04 H01B1/04 

FIELD: chemistry.

SUBSTANCE: polyamide composition contains the following components (wt %): a) 40-99.55 polyamide, b) from 0.15 to 10 electrically conductive carbon, selected from the group of carbon nanotubes and graphene, c) from 0.3 to 8 the oligofunctional compound, that contains at least one functional group, that is capable to react with the reactive groups on the carbon surface, and also optionally at least one functional group, that can react with the terminal group of the polyamide, d) up to 59.55 of final additives. The functional groups are selected from the oxazinone and oxazoline groups.

EFFECT: improved dispersion of carbon nanotubes, graphene and, accordingly, improved electrical conductivity.
