AbstractThis invention relates to permanently stabilized 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 stabilizing activity and, on the other hand, contain one or more reactive groups through which they are able to react with the polymers to be stabilized. Stabilized polymers, preferably polyurethane elastomer filaments, films and coatings with a permanent washing-resistant, boiling resistant, acid-resistant, dry-cleaning-resistant and solvent-resistant stabilization based on 2,2,6,6-tetraalkyl piperidine light stabilizers are thus obtained.
