ABSTRACT:
Compositions based on red phosphorus and a phenolformaldehyde polycondensate.
These compositions contain from 50 to 95% by weight of red phosphorus and from 5 to 50% by weight of a thermoplastic phenol-formaldehyde polycondensate of molecular weight between 120 and 1,500, wherein the molar ratio of formaldehyde to phenol is between 0.7 and 0.9.
These compositions are intended for the flameproofing of plastics and do not evolve toxic products during use.
