  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.

  这项瞬时发明涉及具有至少两个氮原子且碱度不同的受阻胺化合物。其中一部分在N原子上被烷氧基团取代，另一部分在N原子上被一个羟基-烷基基团取代。这些材料在稳定聚合物方面特别有效，尤其是热塑性聚烯烃，可以抵御氧化、热和光辐射的有害影响。这些化合物在稳定酸催化和环境固化的涂层系统方面也特别有效。
