The discovery of inverse vulcanization has allowed stable polymers to be made from elemental sulfur, an unwanted by-product of the petrochemicals industry. However, further development of both the chemistry and applications is handicapped by the restricted choice of cross-linkers and the elevated temperatures required for polymerisation. Here we report the catalysis of inverse vulcanization reactions. This catalytic method is effective for a wide range of crosslinkers reduces the required reaction temperature and reaction time, prevents harmful HS production, increases yield, improves properties, and allows crosslinkers that would be otherwise unreactive to be used. Thus, inverse vulcanization becomes more widely applicable, efficient, eco-friendly and productive than the previous routes, not only broadening the fundamental chemistry itself, but also opening the door for the industrialization and broad application of these fascinating materials.
反硫化的发现使得可以从元素硫（石化工业的一种副产物）中制造稳定的聚合物。然而，由于交联剂的选择受限以及聚合所需的高温，该化学物质及其应用的进一步发展受到了阻碍。在这里，我们报告了反硫化反应的催化作用。这种催化方法对于广泛的交联剂都有效，降低了所需的反应温度和反应时间，防止了有害的 HS 生成，提高了产率，改善了性能，并允许使用原本不反应的交联剂。因此，反硫化比以前的方法更广泛地适用、高效、环保且有生产力，不仅拓宽了基础化学本身，而且为这些迷人材料的工业化和广泛应用打开了大门。
