ABSTRACT:
The invention entitled "Polymers containing polyalkylpiperidines and use thereof as stabilizers" provides a class of polymers in which groups containing sterically hindered polyalkylpiperidines are linked in the main chain of the polymers via bridging members containing 2-hydroxy-1,3-trimethylene groups.
The polymers show superior stabilizing effects for various synthetic polymers such as polyolefins against degradation thereof induced by light and/or heat. The polymers have advantages, as compared with known stabilizer compounds, that they hardly volatile upon processing with heating or during storage of articles containing thereof, and that they are resistant to extraction with solvents from articles containing thereof.
