ABSTRACT:
A process is disclosed for preparing a polysulfide polymer using a heavy ends waste generated in chlorinated hydrocarbon production. The process involves first pretreating the heavy ends waste by an enriching process to form an enriched heavy ends waste with an ethylene dichloride content less than 10% by weight. The enriched heavy ends waste is then reacted with alkaline polysulfide within a temperature range of 50.degree. C. to 150.degree. C. to form a polysulfide polymer.
