FIELD: chemistry.
SUBSTANCE: invention relates to thermoplastic moulding compositions, containing: A) 10-98 wt % thermoplastic polyamide, B) 0.01-20 wt % highly branched melamine polymer or highly branched melamine-carbamide polymer or mixtures thereof, wherein the degree of branching is 10-99.9%, C) 0-70 wt % additives selected from a group including fibrous or granular filler, lubricants, sterically hindered phenols, nigrosine, iron powder, viscoelastic polymerisates, stabilisers, antioxidants, anti-thermal decomposition agents in UV light, lubricants and lubricants for separation from the mould, dye substances, agents for forming crystallisation centres and plasticisers, C3) 0.05-3 wt % copper-containing stabiliser.
EFFECT: invention relates to use of moulding compositions to produce fibres, films and moulded articles; the moulding compositions exhibit improved resistance to heat ageing and a good surface after heat ageing.
