Abstract The effects of the polymerization conditions on the yield of insoluble sulfur were investigated by using olefin, such as the 1,-dodecene, 1,-tetradecene, 1,-octadecene as well as acids, such as the salicylic acid, lauric acid and the oleic acid as polymerization stabilizers. The properties of the as-prepared insoluble sulfur were characterized by mu-Raman spectrometer and differential scanning calorimetry (DSC). The results demonstrated that both the olefin and acid stabilizers could couple with the end groups of the IS, thus improved the thermal stability of the IS, and the olefin stabilizers were superior to the acid stabilizers. The stabilizing effect of oleic acid was the best for the acid stabilizers, and the C C in the oleic acid played a crucial role in the stabilization of the IS.

烯烃和酸稳定剂对不溶性硫磺性质的影响

摘要 以1,-十二碳烯、1,-十四碳烯、1,-十八碳烯等烯烃以及水杨酸、月桂酸、月桂酸等酸为研究对象,研究了聚合条件对不溶性硫收率的影响。油酸作为聚合稳定剂。所制备的不溶性硫的性质通过 mu-Raman 光谱仪和差示扫描量热法 (DSC) 进行表征。结果表明，烯烃稳定剂和酸稳定剂均能与IS的端基偶联，从而提高IS的热稳定性，且烯烃稳定剂优于酸稳定剂。油酸对酸稳定剂的稳定效果最好，油酸中的CC对IS的稳定起到了至关重要的作用。
