Polytriazine compounds having a number average molecular weight from 1000 to 20 000 and containing recurring piperidylamidinotriazine structural units of the formula (IA)
or a combination of said structural units of the formula (IA) with recurring structural units of the formula (IB)
with molar proportions of (IA) and (IB) from 30 % to 100 % for (IA) and 0 to 70 % for (IB), wherein A is a group of the formula (II)
and Li, L2, L3, R1 and R2 are as defined in claim 1, can be used as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials, in particular synthetic polymers.
