Abstract
The present invention relates to the use of aromatic P—N-compounds in flame retardant polymer compositions. These compositions are especially useful for the manufacture of flame retardant compositions based onthermoplastic polymers, especially polyolefin homo- and copolymers, polycondensates, such as polyamines or polyesters and duroplastic polymers, such as polyepoxides.
