标 题 :Process for the Synthesis of Amine Ethers
发明人：FREY MARKUS; BROENNIMANN VALERIE
权利人:CIBA GEIGY CORP
摘要:The present invention relates to novel processes for the preparation of a sterically hindered amine ether by reacting a corresponding sterically hindered amine oxide with a ketone or an aldehyde with at least one reactive H in the presence of a peroxydisulphate. Products obtained by this process may be hydrogenated. The compounds made by these processes are particularly effective in the stabilization of polymer compositions against harmful effects of light, oxygen and/or heat and as flame-retardants for polymers.
