ABSTRACT:
Condensation polymers or addition polymers which contain sterically hindered polyalkylpiperidine groups are proposed as light stabilizers for plastics. The polymers concerned are relatively low-molecular polymers and a difunctional derivative of a polyalkylpiperidine is additionally used for themanufacture of these. The piperidine radical can be present in the main chain or as a side group of the polymeric stabilizer. Polymeric stabilizers of this type do not tend to migrate out of the plastic or to be removed by extraction; they are therefore very permanent in use.
