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 having the formula of R.sup.2 O(CH.sub.2 CH.sub.2 O).sub.7 H as catalyst wherein the dimercaptan is present in excess amount to effect the preparation of the disulfide polymer.
