Halogen-free, flame-retardant polymer foams which comprise, as flame retardant, at least one cyclic or acyclic oligophosphorus compound, and processes for their production. Examples of suitable oligophosphorus compounds are those having the structure Ia, Ib, or Ic:
Another group of suitable oligophosphorus compounds is that having one of the following structures IIa, IIb, or IIc:
Cyclic oligophosphorus compounds of the following structure III are also suitable:
