ABSTRACT:
New derivatives of N,N'-4-piperidyl-tetraalkyl-substituted alkylene diamines are disclosed. These new compounds are useful for stabilizing thermoplastic polymers, in particular polyolefins, against sunlight, heat and oxidation. A process for producing the new compounds is also disclosed, as well as the use thereof as stabilizers of polymers and polymeric compositions.
