FIELD: chemistry.
SUBSTANCE: invention relates to the field of thermoplastic moulding compositions, in particular to a polyamide moulding material widely used for moulding industrial parts, pipes, containers. Polyamide moulding composition contains 40 to 99.9 wt% of components a) copolyamide, b) olefin copolymer and 0.01 to 60 wt% additives. Wherein a) contains 60 - 99 pts.wt copolyamide based on hexamethylenediamine, terephthalic acid and lactam and / or ω-aminocarboxylic acid with 11 or 12 carbon atoms; b) 1-40 pts.wt, contains monomer units based on ethene, 1-alkene with 4-8 carbon atoms or anhydride of an aliphatic unsaturated dicarboxylic acid or based on another olefin.
EFFECT: disclosed moulding composition provides moulded articles with an increased elongation at break even after prolonged use under high temperature conditions while maintaining impact strength and high performance properties.
