s-Triazine compounds, the molecule of which contains at least one ethylenically unsaturated group and at least one 2,2,6,6-tetramethylpiperidine group can be grafted onto organic polymers, in particular onto polyolefines, in the presence of free-radical formers or by means of irradiation. Examples of free-radical formers are peroxy or azo compounds. If polyunsaturated piperidine-triazine compounds are used, it is also possible to achieve crosslinking of the polymer, particularly in the case of polyethylene.
