摘要:
The polyamide polymers, notably the nylons, are effectively heat stabilized, characteristically with good retention of mechanical properties, by formulating therewith stabilizing amounts of (i) at least one lanthanide or yttrium-based compound and (ii) at least one ammonium, or alkali or alkaline earth metal halide.
