Permanently stabilized polymers Abstract of the Disclosure This invention relates to permanently stabilised polymers containing substituted piperidine derivatives chemically attached to the polymer molecule through O- or N-atoms. Compounds based on 2,2,6,6-tetraalkyl piperidines have now been found which, on the one hand, have a very high stabilising activity and, on the other hand, contain one or more reactive groups through which they are able to react with the polymers to be stabilised. Stabilised polymers, preferably polyurethane elastomer filaments, films and coatings with a permanent washing-resistant, boiling resistant, acid- resistant, dry-cleaning-resistant and solvent-resistant stabilisation based on 2,2,6,6-tetraalkyl piperidine light stabilisers are thus obtained.
