25 g of 2,2,6,6-tetramethyl-4-hydroxymethyl-piperidine of Example 1 (0.146 moles) were dissolved in 50 cc of methanol and added with 8 g (0.18 moles) of ethylene oxide. The solution was introduced into a steel autoclave and heated under stirring during 6 hours at 120° C. Then the solvent was evaporated and the residue was crystallized from acetonitrile. 30 g of product having a M.P. of 81°-83° C. were obtained, the product being characterized by N.M.R. and I.R. analyses and recognized as the product intended to be obtained.
