Novel process for the preparation of 2,2,6,6-tetramethyl-4-piperidyloxy-1.3.5-tr iazines with two or more triazine rings Novel process for the preparation of 2,2,6,6-tetramethyl-4-piperidyloxy-1,3,5-tr iazines, based on Ihe reaction of cyanuric chloride with C1-C4alkanols or with sodium or potassium C1-C4alkoxides and subsequent reaction with 2,2,6,6-tetramethyl-4-piperidinols in the presence of a transesterification catalyst. The various reactions can be carried out in the same reactor, without isolation of the intermediates. Formula (I) <IMG>
