| 摘要 |
Isocyanurate esters of carboxyalkylthioalkanoesterphenols useful in the stabilization of organic materials normally susceptible to oxidative degradation are prepared by reacting an appropriate isocyanurate trithiol, which is a selected tris-mercapto alkanoic acid ester of tris-(2-hydroxyethyl) isocyanurate with an appropriate alkenyl compound, which is a selected 4-hydroxy-(mono- or di-alkyl)phenyl alkyl alkenoate. In a preferred embodiment, the ester is 1,3,5-tris [( 3,5-di-tert-butyl-4-hydroxyphenyl)-(3-propyl) oxycarbonylethylthiopropionyloxyethyl] isocyanurate.
