Abstract
This invention is directed to polymeric compounds which contain the polyalkylpiperidine radical and at least two primary hydroxyl groups. These compounds are useful as light stabilizers for plastics and coatings. More particularly, the polymeric stabilizers is formed by chain extending polyalkylpiperidine with an excess of epoxy resin to form a diepoxide functional polymer which is then capped with hydroxy functional monomer.
