摘要： The present invention relates to a novel process for the preparation of a sterically hindered nitroxyl ether from the corresponding sterically hindered nitroxyl radical by reacting it with a carbonyl compound and a hydroperoxide. The compounds prepared by this process are effective stabilizers for polymers against harmful effects of light, oxygen and/or heat, as flame-retardants for polymers and as polymerization regulators.
摘要翻译： 本发明涉及通过与羰基化合物和氢过氧化物反应从相应的空间位阻硝酰基制备空间位阻硝酰基醚的新方法。 通过该方法制备的化合物是聚合物抗光，氧和/或热的有害作用的有效稳定剂，作为聚合物的阻燃剂和聚合调节剂。
