  • Publication number: 20120108709
    Abstract: The instant invention pertains to sterically hindered amine Night 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 dine ring (Spiro-NOR-HALS). These compounds are particularly effective in stabilizing polymers, especially thermoplastic polyolefins, against the deleterious effects of oxidative, thermal and actinic radiation. The compounds are also particularly effective in stabilizing acid catalyzed and ambient cured coatings systems. They are particularly useful when high processing temperatures are additional required.

  • Publication number: 20120083557
    Abstract: The instant invention pertains to hindered amine compounds having at least two nitrogen atoms with different basicity. One part is substituted on the N-atom by alkoxy moieties and the other part is substituted on the N-atom by a hydroxy-alkyl moiety. These materials are particularly effective in stabilizing polymers, especially thermoplastic polyolefins, against the deleterious effects of oxidative, thermal and actinic radiation. The compounds are also particularly effective in stabilizing acid catalyzed and ambient cured coatings systems.

  • Publication number: 20110160453
    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.
