Abstract: of the disclosure: The invention relates to copolymers of polyalkyl piperidines which are substituted by a polymerizable group and which have the formula with olefinic comonomers such as ethylene, styrene, vinyl acetate, acrylates or methacrylates. The copolymers which have a molecular weight of from 1,000 to 10,000 are used as light stabilizers fast to migration for synthetic polymers.
