| titleOfInvention | UV-light-stabilized compositions containing substituted 1,5-diazacycloalkanes and 2-keto-1,5-diazacycloalkanes, novel compounds and synthesis thereof |
| abstract | Novel polysubstituted 1,5-diazacycloalkanes and polysubstituted 2-keto-1,5- diazcycloalkanes 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 N' and N<sup>5</sup> atoms of the diaza ring, the remaining portion of the ring having a variable length bridge of two or more carbon stoms, (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-diazscycloalkanes, exhibit excellent stability to UV light.A novel synthesis for preparing polysubstituted 2- keto-1,5- diazacycloalkanes is disclosed. |
