Abstract
This invention relates to a new process for the preparation of N-polythiodimorpholines wherein morpholine and elemental sulfur in an alcohol mixture are oxidized with an alkali metal hypohalite or an alkaline earth metal hypohalite or N-chloromorpholine to yield N-polythiodimorpholines. The process produces N-polythiodimorpholines without the use of corrosive or toxic chemicals and the product is an economical substitute for conventional rubber curatives.
