The mixture is warmed at room temperature for a further 4 hours.
27.2 g (0.128 mol) of N-(2,2,6,6-tetramethyl-4-piperidyl)butylarriine are added and the resultant mixture is warmed at 60°C for 2 hours. A further 18 g (0.13 mol) of anhydrous potassium carbonate are added and the mixture is warmed at 60°C for a further 6 hours. The solvent is removed by distillation under a slight vacuum (200 mbar) and replaced by xyfene. 18.2 g (0.085 mol) of N-(2,2,6,6-tetra methyl-4-piperidyl)butylamine and 5.2 g (0.13 mol) of ground sodium hydroxide are added, the mixture is heated at reflux for 2 hours and, for a further 12 hours, the water formed during the reaction is removed by azeotropic distillation. The mixture is filtered. The solution is washed with water and dried over NaZS04. The solvent is evaporated and the residue is dried at 120-130°C in vacuo (0.1 mbar).
The desired product is obtained as a colourless resin.
In general, the product (C-6) can for example be represented by a compound of the formula (C-6-a), (C-6-[i) or (C-6-'y). It can also be in the form of a mixture of these three compounds.

100 parts of unstabilized polypropylene powder (melt flow index: 3.8 g/10 min at 230°C and 2160 g) are homogenized at 200°C for 10 min in a Brabender plastograph with 0:05 parts of pentaerythrityl-tetrakis{3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate}, 0.05 parts of tris(2,4-di-tert-butylphenyl) phosphite, 0.1 parts of Ca stearate, 0.25 parts of titanium dioxide (Anatase) and the stabilizer mixture indicated in Table 1. The material thus obtained is compression molded in a laboratory press between two aluminum foils for 6 min at 260°C to a 0.5 mm thick film which is cooled immediately to room temperature in a water-cooled press. Samples of 60 mm x 25 mm are cut out of these 0.5 mm films and are exposed in a WEATHER-OMETER Ci 65 (black panel temperature 63~2°C, without water-spraying).
Periodically, these samples are removed from the exposure apparatus and their carbonyl content is measured with an infrared spectrophotometer. The exposure time corresponding to formation of a carbonyl absorbance of 0.1 is a measure for the efficiency of the stabilizer mixture. The values obtained are summarized in Table 1.

All stabilizer mixtures described in this application are further useful as light stabilizers for coatings. A use in combination with an UV absorber is preferred. Suitable coatings are for example described in US-A-6,117,997, column 26, line 55 to column 32, line 21.
The example below illustrates the use of the second stabilizer mixtures. All percentages and parts are by weight, unless stated otherwise.
Example A: Light stabilization of polypropylene homopolymer films.
100 parts of unstabilized polypropylene powder (melt flow index: 3.2 g/10 min at 230°C and 2160 g) are homogenized at 200°C for 10 min in a Brabender plastograph with 0.05 parts of pentaerythrityl-tetrakisf3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate), 0.05 parts of tris{2,4-di-tert-butylphenyl) phosphite, 0.1 parts of Ca stearate, 0.25 parts of titanium dioxide (Anatase) and the stabilizer mixture indicated in Tables 3a and 3b. The material thus obtained is compression molded in a laboratory press between two aluminum foils for 6 min at 260°C to a 0.5 mm thick film which is cooled immediately to room temperature in a water-cooled press. Samples of 60 mm x 25 mm are cut out of these 0.5 mm films and are exposed in a WEATHER-OMETER Ci 65 (black panel temperature 63~2°C, without water-spraying).
Periodically, these samples are removed from the exposure apparatus and their carbonyl content is measured with an infrared spectrophotometer. The exposure time corresponding to formation of a carbonyl absorbance of 0.1 is a measure for the efficiency of the stabilizer mixture. The values obtained are summarized in Tables 3a and 3b.
