  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.

  本发明涉及具有至少两个具有不同碱性的氮原子的受阻胺化合物。其中一部分在N原子上被烷氧基团取代，另一部分在N原子上被羟基烷基团取代。这些材料在稳定聚合物，特别是热塑性聚烯烃，抵抗氧化、热和光辐射的有害影响方面特别有效。这些化合物也特别有效地稳定酸催化和室温固化的涂层系统。
