ABSTRACT:
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 stabilization of polymers, preferably of polyolefins, against thermal-oxydative attack. The compounds themselves exhibit a good stability against discoloration by radiation or gas fading.
