The present invention relates to the use of NOR-HALS compounds in flame retardant polymer compositions. These compositions are especially useful for the manufacture of flame retardant compositions based on thermoplastic polymers, especially polyolefin homo- and copolymers, polycondensates, such as polyamines or polyesters and duro-plastic polymers, such as polyepoxides.

NOR-HALS compounds as flame retardants

The present invention relates to oxygen-substituted sterically hindered amines of the formulae I or II: (II), wherein, for example, F, R, R, R, R, R, R, R, R, Rare n-butyl: Zto Zare propoxy and R, R, R, R, Rare 2,2,6,6-tetramethyl-1-propoxy-piperidin-4-yl. Compositions comprising compounds of formulae I or II and an organic material, which is susceptible to oxidative, thermal or light-induced degradation, are further disclosed. Optionally, further additives are contained.
