  • Patent number: 9045480
    Abstract: The disclosure concerns sterically hindered amine light stabilizers (HALS) with low basicity at the nitrogen atom and high thermal stability. They are characterized by their spiro-substitution in the 4-position of the tetramethylpiperidine ring (Spiro-NOR-HALS). These compounds are useful in stabilizing polymers, especially thermoplastic polyolefins, against the deleterious effects of oxidative, thermal and actinic radiation. The compounds are also useful in stabilizing acid catalyzed and ambient cured coatings systems. They are particularly useful when high processing temperatures are additional required.

  • Patent number: 8481726
    Abstract: The present invention relates to a novel process for the preparation of specific sterically hindered nitroxyl ethers from their corresponding sterically hindered nitroxyl radicals by reacting it with an aldehyde and a hydroperoxide. This nitroxyl ether formation may be carried out from different starting nitroxyl radicals, which are subsequently further reacted to the desired compounds. The compounds prepared by this process are effective as stabilizers for polymers against harmful effects of light, oxygen and/or heat and as flame-retardants for polymers.
