Abstract

A composition, which comprises a) an organic material susceptible to oxidative, thermal or light-induced degradation; and b) a compound of formula I (Formula I) (I) where R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 and R 10 are independently from each other H, C 1 -C 8 -alkyl, C 4 -C 8 -cycloalkyl, phenyl, C 1 -C 4 -alkoxy or halogen; n is 1, 2, 3, or 4; and when n is 1 A is —C(=0)-OR′ 1 , —C(=0)-N(R ′2 )(R′ 3 ), —CN, phenyl, which is unsubstituted or substituted by one or more C 1 -C 8 -alkyl, C 4 -C 8 -alkoxy, C 5 -C 7 -cycloalkyl or halogen, —H or —S0 2 -phenyl; when n is 2 A is —C(=0)-0-Z 1 —O—C(=0)-, —C(=0)-N(R″ 1 )—Z 2 —N(R″ 2 )—C(=0)- or piperazine-N,N′-biscarbonyl.

First claim

The invention claimed is:

1. A composition comprising
a) a polyolefin, a polyester polyol, or a polyurethane;
b) compound having a structure,

 and
c) an additive selected from the group consisting of a phosphite, a phosphonite, an acid scavenger, a phenolic antioxidant, and an aminic antioxidant.

2. A composition according to claim 1 , wherein component b) is contained in an amount of 0.005% to 10% based on the weight of component a).

3. A composition according to claim 1 , wherein the weight ratio of b) to c) is from 4:1 to 1:20.

4. A composition according to claim 1 , wherein additive c) selected from the group consisting of a phosphite, and a phenolic antioxidant.

5. A process for protection of a polyolefin, a polyester polyol, or a polyurethane susceptible to oxidative, thermal or light-induced degradation comprising incorporating into or applying onto the polyolefin, polyether polyol, or polyurethane a compound having a structure

and
an additive selected from the group consisting of a phosphite, a phosphonite, an acid scavenger, a phenolic antioxidant, and an aminic antioxidant.
