Abstract
Novel 4-(3,5-dialkyl-4-hydroxyphenyl)-1,2-dithiole-3-thiones are used as additives for organic materials. They are prepared by reacting a corresponding alkylated phenol with sulfur and if necessary reacting the resulting compound with sodium disulphide and then with a corresponding halide.
