Abstract

Use of one or more amino-triazine based Mannich-compounds and/or their dimers or trimers and/or one or more precondensate therefrom, including special new amino-triazine based Mannich-compounds, as antioxidant and/or UV-stabilizer for organic material, preferably for polymers; the stabilized material and use of the stabilized material.

First claim

The invention claimed is:

1. A method of stabilizing one or more polyolefins against degradation comprising the step of incorporating into said material an amino-triazine based Mannich-compound according to formula (I)

dimers or trimers and precondensate therefrom according to formula (II)

or mixtures thereof, in an amount effective to stabilize said organic material, wherein
A is O, N or S,
R 4 is hydrogen or Q 1 or a group R 5 —N—R 6 bonded with its central nitrogen atom to the triazine ring of structure (I) or (II),
R 1 , R 2 , R 3 , R 5 and R 6 are hydrogen, or Q 1 or group of the formula (III)

R 7 is hydrogen or Q 1 , wherein when A is O or S, R 7 is present once, and when A is N, R 7 is present twice,
each R 8 is independently selected from another and can be Q 1 , or is selected from a group consisting of substituted or non-substituted hydroxyl; substituted or non-substituted amino; halogen; substituted or non-substituted sulphur; and a group with the structure of (IV),

whereby R 8′ has the meaning of R 8 whereby R 8′ is not also structure (IV),
n is 1 or 2, whereby the position of R 8 n is ortho to AR 7 ,
Q 1 is selected from the group consisting of substituted and non-substituted, linear or branched C 1 -C 50 -alkyl, substituted and non-substituted, linear or branched C 2 -C 50 -alkenyl, substituted and non-substituted, linear or branched C 2 -C 50 -alkinyl, substituted and non-substituted C 3 -C 10 -cycloalkyl, substituted and non-substituted C 5 -C 7 -cycloalkenyl, and substituted and non-substituted C 6 -C 20 -aryl, which in each case can be interrupted by one or more atoms or groups selected from the group consisting of oxygen atoms, sulphur atoms, substituted nitrogen atoms, double bonds, siloxan groups and/or by one or more groups of the type —C(O)O—, —OC(O)—, —C(O)—, —C(O)NH—, —OC(O)NH—, and/or —OC(O)O—, wherein in case of R 4 the atoms and groups selected from oxygen atoms, sulphur atoms, —OC(O)—, —C(O)—, —NHC(O)O—, —NHC(O)NH— or —OC(O)O— can be directly connected to the triazine ring and in case of R 7 the atoms and groups selected from —C(O)—, C(O)O— or —C(O)NH— can be directly connected to A and in case of R 8 the groups selected from —OC(O)—, —C(O)—, —NHC(O)O—, —NHC(O)NH—, —C(O)O—, —C(O)NH— or —OC(O)O— can be directly connected to the aromatic ring,
m is 2 to 20.

2. The method of claim 1 , wherein in the formula (I) and (II):
A is O or N,
R 4 is Q 1 , Q 1 being selected from the group consisting of substituted or non-substituted, linear or branched C 1 -C 18 -alkyl; substituted or non-substituted C 6 -C 10 -aryl; or a group R 5 —N—R 6 bonded with its central nitrogen atom to the triazine ring of structure (I) or (II), with R 5 and R 6 being selected from the group consisting of hydrogen; substituted or non-substituted, linear or branched C 1 -C 12 -alkyl; substituted or non-substituted C 3 -C 7 -cycloalkyl; and substituted or non-substituted, linear or branched C 2 -C 12 -alkenyl,
R 1 , R 2 and R 3 are selected from the group consisting of hydrogen, substituted or non-substituted, linear or branched C 1 -C 18 -alkyl, substituted or non-substituted C 3 -C 7 -cycloalkyl, substituted or non-substituted, linear or branched C 2 -C 12 -alkenyl, and the group of the formula (III)

R 7 is one of hydrogen or C 1 -C 12 -alkyl which can be interrupted by one or more oxygen atoms, substituted nitrogen atoms, and/or by one or more groups of the type —C(O)O—, —OC(O)— and —C(O)—, whereby the group —C(O)— can also be directly connected to A,
R 8 is selected from the group consisting of —OH; —OCH 3 ; —OC 2 H 5 ; —NH 2 ; substituted or non-substituted, linear or branched C 1 -C 12 -alkyl; substituted and non-substituted C 3 -C7-cycloalkyl; substituted and non-substituted, linear or branched C 2 -C 12 -alkenyl; and substituted and non-substituted C 6 -C 12 aryl,
m is 2 to 10.

3. The method of claim 1 , wherein said compounds of formula (I) and (II) are selected from the group consisting of:

and combinations thereof.

4. The method of claim 1 , wherein said degradation is oxidative degradation.

5. The method of claim 1 , wherein said degradation is ultraviolet degradation.

6. The method of claim 1 , further comprising the step of introducing one or more hindered amine light stabilizers to said organic material with said amino-triazine based Mannich-compound.

7. A method of stabilizing one or more polyolefins against oxidative and ultraviolet degradation comprising the step of incorporating into said material an amino-triazine based Mannich-compound according to formula (I)

dimers or trimers and precondensate therefrom according to formula (II)

or mixtures thereof, in an amount effective to stabilize said organic material, wherein
A is O, N or S,
R 4 is hydrogen or Q 1 or a group R 5 —N—R 6 bonded with its central nitrogen atom to the triazine ring of structure (I) or (II),
