39 Examples of carrying out the process according to the invention are given below.

Example 1. A mixture consisting of 10.26 parts by weight 1,2,2,6,6-pentamethylpiperidin-4-ol, 6.06 parts by weight sebacic acid, 1.0 parts by weight titanium tetra-n- butyl and 100 parts by weight xylene is heated under reflux for a period of 60 hours. After removal of xylene by distillation under reduced pressure, an oily substance is obtained, which is treated with 0.5 parts by weight sodium carbonate, 0.5 parts by weight coal and 25 parts by weight water, the resulting mixture being then boiled under reflux over a period of one hour. After removal of the water by distillation under reduced pressure, a black residue is obtained, which is extracted several times with ether.

The ethereal extracts are combined and dehydrated, and the eiter is removed by distillation under reduced pressure, to obtain a yellow oil, which is distilled under reduced pressure, to give 5.0 parts sebacate bis (l, 2,2,6,6-pentamethyl-4-piperiidinyl) as an oil. colorless with a boiling point of 220 ... 222 ° C, under a vacuum of 0.2 mm Hg and with the following elemental analysis (¼ mass):

- calculated: C = 70.82; H, 11.10; N, 5.51;

- Found: C, 70.60; H = 11.00; N, = 4.81.

Instead of xylene, benzene or toluene can be used as a solvent.
