The invention relates to flame retardant compositions, wherein a phosphinic acid hydrazide is present in a polymer substrate. The combination with >NOR-compounds improves the flame retardant properties. 4. A composition according to claim 1 , which comprises as Component a) a compound (I) claim 1 , wherein{'sub': 1', '2', '1', '20', '6', '20', '1', '12', '6', '20', '6', '20', '1', '4, 'Both Rand Rindependently of one another represent substituents selected from the group consisting of C-Calkyl, C-Caryl, C-Calkyl-C-Caryl and C-Caryl-C-Calkyl; and'}R represents hydrogen or a group of the partial formula (A),{'sub': 1', '2', '1', '2, 'Wherein R′ and R′ are defined as Rand R,'}or a salt thereof.5. A composition according to claim 1 , which comprises as Component a) a compound (I) claim 1 , wherein{'sub': 1', '2', '1', '8, 'Both Rand Rindependently of one another represent substituents selected from the group consisting of C-Calkyl and phenyl; and'}R represents hydrogen or a group of the partial formula (A),{'sub': 1', '2', '1', '2, 'Wherein R′ and R′ are defined as Rand R,'}or a salt thereof.6. A composition according to claim 1 , which comprises{'claim-ref': {'@idref': 'CLM-00001', 'claim 1'}, 'a) A compound (I) according to , wherein'}{'sub': 1', '2', '1', '8, 'Both Rand Rindependently of one another represent substituents selected from the group consisting of C-Calkyl and phenyl; and'}R represents hydrogen or a group of the partial formula (A), wherein{'sub': 1', '2', '1', '2, 'R′ and R′ are defined as Rand R,'}or a salt thereof; andb) A thermoplastic polymer substrate.7. A composition according to claim 1 , which further comprises an additional flame retardant or an additive selected from the group consisting of polymer stabilizers claim 1 , tetraalkylpiperidine derivatives and tetraalkylpiperazine derivatives.8. A composition according to claim 1 , which comprises as an additional flame retardant a nitrogen containing compound selected from the group consisting of ...
