With the synthesis and characterization of the poly(trisulfide) polymer established, its depolymerization was investigated next (Figure ). Accordingly, the polymer was suspended in anhydrous DMF and then excess dimethyl trisulfide was added (~40 equivalents relative to the number of trisulfides in the polymer). The reaction was stirred for 5 minutes, but 1 minute of reaction time was sufficient for GPC analysis to indicate complete depolymerization (S252-S254). The regenerated monomer was extracted and the excess dimethyl trisulfide recovered by distillation. The monomer was recovered in excellent purity and in 91% yield.
