Sulfur polymers were synthesised via “inverse vulcanisation” polymerisation, involving the addition of an aromatic, divinylic cross-linker (1,3-diisopropenyl benzene or limonene) to molten elemental sulfur. This reaction forms a red, intractable solid which was then annealed under a flow of nitrogen at 750 C yielding a highly porous, sulfur-carbon framework. Several S-polymers with differing wt. % ratios of sulfur to 1,3-diisopropenyl benzene were examined.
