Abstract
The invention relates to flame retardant compositions comprising heptaphosphorus-derived compounds and to novel heptaphosphorus-derived compounds. These heptaphosphorus-derived compounds are especially useful for the manufacture of flame retardant compositions based on thermoplastic polymers, especially polyolefin homo- and copolymers, polycondensates, such as polyamides, or polyesters and duroplastic polymers, such as the ones based on polyepoxides.
