<p>The invention relates to the use of a metal powder as a heat stabilizer in preparing thermostabilized thermoplastic moulding compositions, wherein the metal powder has a weight average particle size (dm) of at most 1 mm and the metal in the metal powder is selected from the group consisting of elementary metals from Group VB, VIB, VIIB and VIIIB of the Periodic Table, and mixtures thereof. The invention also relates to non-fibrous-reinforced thermoplastic moulding compositions comprising the said metal powders, and next to that a thermoplastic polymer with an Mw of at most 50.000 g/mol, or a blend of at least two thermoplastic polymers with Tmelt or Tg differing by at least 20 °C, or a second thermostabilizer. The invention also relates to fibrous-reinforced thermoplastic moulding compositions comprising the said metal powders and a fibrous reinforcing agent.</p> |
