ABSTRACT:
A process for preparing an organic disulfide polymer such as polyethylene disulfide which is used in batteries comprises contacting a dimercaptan such as 1,2-ethanedithiol with elemental sulfur using a mixture of a basic compound such as NaOH and an ethoxylated alcohol such as Union Carbide's TERGITOL.RTM. 15-S-7 as catalyst wherein the dimercaptan is present in excess amount to effect the preparation of the disulfide polymer.
