ABSTRACT:
Polymers containing polyalkylpiperidines, preparation and use thereof as stabilizers for synthetic polymer compositions are described. In said polymer, sterically hindered polyalkylpiperidines are laterally linked to the main chain. The polymers are distinguished by an improved stabilizing effect in various synthetic polymer compositions, such as polyolefins, against light- and/or heat-induced deterioration thereof. The polyalkylpiperidine-containing polymers of the invention are hardly volatile upon heat-processing or during storage of shaped articles containing said polymers, and are resistant to extraction with solvents.
