Abstract:

Elemental sulfur, which is a by-product of crude oil, is a widely available, cost-effective element. The excess of the elemental sulfur increased the interest of researchers on different application of this element. Herein, sulfur content-crosslinked porous polymer networks were synthesized via two-step procedure combining emulsion templating and inverse vulcanization. For this purpose, β-myrcene was copolymerized with ethylene glycol dimethacrylate (EGDMA) by using high internal phase emulsion (HIPE) templating approach to synthesize hierarchical porous polyHIPEs, firstly. Then, inverse vulcanization was used as a post-polymerization process to consume the remaining –ene structures on the resulting crosslinked copolymer network. The formation of highly crosslinked, sulfur containing polyHIPE network was verified via FTIR, 1H NMR and elemental analysis. Accordingly, it was demonstrated that the specific surface area and thermal properties of the polyHIPE networks can be easily improved by using inverse vulcanization approach without compromising the pore morphology.

Keywords: Sulfur content polymers; Emulsion templating; Inverse vulcanization; β-myrcene
