Tetrakis(2,6-di-t-butyl-4-substituted phenyl)4,4'-substitutedbisphenyl diphosphites that are prepared from a hindered phenol and a non-hindered bisphenol have been found to be excellent stabilizers for organic materials subject to degradation, and form even more effective combinations with hydroxyphenylalkyleneyl isocyanurates, substantially and synergistically enhancing the stabilizing efficiency of the isocyanurate.
由受阻酚和非受阻双酚制备的四(2,6-二-t-丁基-4-取代苯基)4,4'-取代双苯基二膦酸酯已被发现是有机材料稳定剂的优秀选择,与羟基苯基烷基异氰酸酯形成更有效的组合,显著且协同地增强异氰酸酯的稳定效率。
