The new N-[3-(3-hydroxyaryl)-2-hydroxypropyl]-imides may be prepared by reacting 3-(3-hydroxyaryl)-propenoxides with cyclic imides. These hydroxy compounds as well as their esters with carboxylic acids are highly effective in the stabilisation of polymers, preferably of polyolefins, against thermal-oxydative attack. The compounds themselves exhibit a good stability against discoloration by radiation or gas fading.
新的N-[3-(3-羟基芳基)-2-羟基丙基]-苯并咪唑可以通过将3-(3-羟基芳基)-丙烯氧化物与环状苯并咪唑反应来制备。这些羟基化合物以及它们与羧酸的酯类在聚合物的稳定化方面表现出高效性,特别是对聚烯烃的热氧化攻击。这些化合物本身对辐射或气体褪色表现出良好的稳定性。
