Abstract
Abstract Novel compounds having two bis (2,2,6,6-tetramethyl-4-piperidyl)-substituted nitrogen heterocyclic rings are provided which are useful as stabilizers for organic polymers. Organic polymer containing the novel compounds having two bis (2,2,6,6-tetramethyl-4-piperidyl)-substituted nitrogen heterocyclic ring compounds exhibit improved resistance to deterioration induced by light, by heat or by a combination of light and heat.
