FIELD: chemistry.
SUBSTANCE: composition contains the following (wt %): aliphatic polyamide (up to 100) and a modifying additive (15-45) - functionalised polymer or ethylene-polyethylene copolymer and(or) copolymer of ethylene with C3-8 α-olefin. The functionalised polymer or copolymer contains not less than two carboxylic (or derivatives thereof) groups in the composition of macromolecules. Their melt flow index at temperature for mixing with aliphatic polyamide is 5-50 times lower than the melt flow index of the latter.
EFFECT: invention enables to obtain polyamide compositions which are suitable for processing using extrusion technologies, having high strength and viscosity of the melt.
