A process is described for polymerizing ethylenically unsaturated sterically hindered amines of the polyalkylpiperidine type (HALS) by means of metallocene catalyst, novel polymers resulting therefrom and novel unsaturated HALS. The novel monomeric or copolymeric compounds can be employed advantageously for stabilizing organic material against the damaging effect of light, oxygen and/or heat.
