Abstract
This invention relates to a process for preparing polysulfide product generally containing an average of 3 to 6 sulfur atoms in high yield which degrades minimally over extended time periods. Minimal degradation is accomplished by a unique treatment process wherein chemical species, most notably unreacted mercaptans and catalysts which apparently promote degradation, are selectively removed from the polysulfide crude product.
