(57) Abstract: [configuration] following formula I or formula II: T-CH 2 -CH = CH-CH 2 -T (I) T-CH 2 -CH = CH = CH 2 -N (E 1) ( E 2 ) (II) (In the formula, T represents a 2,6-diarylpiperidin-1-yl moiety; E 1 and E 2 independently represent an alkyl group, a cycloalkyl group, an aralkyl group or an aryl group. ) A novel 2,6-diarylpiperidin-1-yl-substituted 2-butene compound represented by [Effect] The above compounds are excellent as stabilizers against harmful effects of organic materials such as polyolefins and elastomers due to oxygen, heat and actinic radiation. |
