ABSTRACT:
Thermoplastic polymers, such as polypropylene, are rendered anti-flaming and self-extinguishing by addition of ammonium or amine phosphate and a nitrogen-containing water-insoluble oligomer or polymer containing in the monomeric unit a --CO--group attached to a ##STR1## group, wherein n is 2 or 3, being part of a ring, e.g., poly(carbonylpiperazine).
