ABSTRACT:
The invention relates to copolymers of polyalkyl piperidines which are substituted by a polymerizable group and which have the formula ##STR1## 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 for synthetic polymers which do not migrate to the surface of the polymers.
