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:UV-Light-stabilized compositions containing substituted 1,5-diazacycloalkanes, novel compounds and synthesis thereof
发明人：LAI JOHN T; SON PYONG N
权利人:GOODRICH CO B F
摘要:Novel polysubstituted 1,5-diazacycloalkanes and polysubstituted 2-keto-1,5-diazacycloalkanes are powerful stabilizers for materials subject to ultraviolet (UV) light degradation, particularly for polyolefins. The cyclic compounds of this invention have (a) a fixed three-carbon bridge between the N1 and N5 atoms of the diaza ring, the remaining portion of the ring having a variable length bridge of two or more carbon atoms, (b) an N-adjacent carbon atom of the diaza ring is polysubstituted, that is, has two substituents which may be cyclizable. Compositions containing (a) the polysubstituted 1,5-diazacycloalkanes and polysubstituted 2-keto-1,5-diazacycloalkanes of this invention, and (b) prior art polysubstituted 1,5-diazacycloalkanes and polysubstituted 2-keto-1,5-diazacycloalkanes, exhibit excellent stability to UV light. A novel synthesis for preparing polysubstituted 2-keto-1,5-diazacycloalkanes is disclosed.
