Inverse vulcanization utilizes an organic compound as reagent for crosslinking elemental sulfur to result in corresponding polymeric material with a high sulfur content. This work, employing 1,3,5-triisopropylbenzene (TIPB) as the reagent, demonstrates the first attempt on extending the scope of crosslinking agents of inverse vulcanization to saturate compounds. Under nuclear magnetic spectroscopic analysis, the reactions between TIPB and elemental sulfur take places through ring-opening reaction of S₈ resulting in sulfur radicals at sulfur chain ends, radicals transferring to isopropyl groups of TIPB, and radical coupling reactions between carbon radicals and sulfur radicals. The obtained products are similar to the sulfur polymers from conventional inverse vulcanization processes and show self-healing property.

1,3,5-三异丙基苯与单质硫的反应扩大了逆硫化试剂的范围

逆向硫化利用有机化合物作为交联元素硫的试剂，以产生具有高硫含量的相应聚合物材料。这项工作采用 1,3,5-三异丙基苯 (TIPB) 作为试剂，首次尝试将反硫化交联剂的范围扩展到饱和化合物。_{在核磁谱分析下，TIPB与单质硫的反应是通过S 8}的开环反应发生的在硫链末端产生硫自由基，自由基转移到TIPB的异丙基上，碳自由基和硫自由基之间发生自由基偶联反应。所得产物与传统逆硫化工艺中的硫聚合物相似，具有自愈性。
