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) partly aromatic copolyamide, b) olefin copolymer and 0.01 to 60 wt% additives. Wherein a) contains 60 to 99 pts.wt of said copolyamide based on hexamethylenediamine, terephthalic acid and an aliphatic dicarboxylic acid having 8 to 19 carbon atoms, b) contains from 40 to 1 pts.wt of an olefin copolymer containing monomers based on ethene, 1-alkene with 4 to 8 carbon atoms, anhydride of an aliphatic unsaturated dicarboxylic acid, and, optionally, based on another olefin.
EFFECT: disclosed moulding composition provides moulded articles with an increased elongation at breakage after prolonged use at elevated temperatures while maintaining high performance properties.
