The invention relates to a composition comprising an organic material susceptible to oxidative, thermal or light-induced degradation and a compound of formula I-P, I-O or I-M. Further embodiments are a compound of formula I-P, I-O or I-M, a process for protection of the organic material by the compound, the use of the compound against degradation of the organic material, an additive composition comprising the compound, processes for manufacturing the compound and an intermediate involved therein.

3-phenyl-benzofuran-2-one diphosphate derivatives as stabilizers

The invention relates to a composition comprising an organic material susceptible to oxidative, thermal or light-induced degradation and a compound of formula (I-P), (I-O) or (I-M). Further embodiments are a compound of formula (I-P), (I-O) or (I-M), a process for protection of the organic material by the compound, the use of the compound for stabilizing the organic material, an additive composition comprising the compound and a process for manufacturing the compound. The organic material is for example a polymer. 

3-phenyl-benzofuran-2-one derivatives containing phosphorus as stabilizers

A multifilament, a monofilament, a non-woven or a tape, each having 1 to 2000 Denier per filament and a draw ratio of 1:2 to 1:11 and each made of a composition containing the components  

Multifilament, monofilament, non-woven or tape

Organic polymer compositions can be made flame-retardant by addition of selected organic phosphate and other components, such as known flame-retardants or conventional additives for further improvements, e.g. in flame retardancy or light stability.

Flame-retardants

Organic materials which possess outstanding stability to oxidative, thermal or light-induced degradation comprise as stabilizers at least one compound of the benzofuran-2-one type and at least one compound of the sterically hindered amine type.

Phenol-free stabilization of polyolefin fibres

Stabilized filled polyolefins

Described are compositions comprising (a) 25 to 99% of organic phosphite or phosphonite, based on the total weight of the composition, (b) an effective stabilizing amount of organic amine, and (c) an effective stabilizing amount of acid-binding metal salt, wherein said composition comprises no organic polymers or alkali metal phosphates as further components, as well as a process for stabilising organic phosphites or phosphonites against hydrolysis by addition of organic amine and acid-binding metal salt. The compositions are distinguished by their excellent stability to hydrolysis and have good storage stability even at high atmospheric humidity. The novel compositions and process products can be used with advantage as stabilisers for organic material against the harmful action of heat, oxygen and/or light.

Enhancement of the storage stability of organic phosphites and

Recycled mixed plastics from domestic and commercial waste can be stabilized against thermal oxidative degradation by adding a combination of a sterically hindered phenol with a phosphite or phosphonite.
