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.

标题 :Synthesis by reacting oxirane resin with carboxyl compounds
发明人：DAMMANN LAURENCE G
权利人:ASHLAND OIL INC
摘要:Disclosed is a new partial capping synthesis wherein resinous mixtures containing controlled amounts of phenolic hydroxyl and/or mercapto functionality, and aliphatic hydroxyl functionality are synthesized. Such synthesis comprises providing one or more resins which in total contain aliphatic primary and/or secondary hydroxyl functionality and oxirane functionality. A single resin or blend of resins may provide the requisite functionality. The one or more resins then are reacted with a carboxyl-functional capping agent bearing phenolic hydroxyl functionality and/or mercapto functionality. This reaction is conducted under reaction conditions and for a time such that the carboxyl functionality of the capping agent selectively reacts with the oxirane functionality of the one or more resins to produce a resinous product containing aliphatic hydroxyl functionality and containing phenolic hydroxyl functionality and/or mercapto functionality.
