This study investigated the corrosion test of nitrile-butadiene rubber (NBR) in H₂S. Butadiene rubber (BR) and hydrogenated nitrile-butadiene rubber (HNBR) were used to simulate the structural units of 1,4-polybutadiene and polyacrylonitrile in NBR. The characterizations of infrared spectra, CHNS elemental analysis, and XPS may indicate that when double bonds and nitrile groups coexist, NBR has the highest reactivity with H₂S and crosslinks of monosulfur and disulfide appear inside the rubber. However, the reactivity of BR and HNBR was reduced and no crosslinking was produced when both were isolated. Therefore, double bonds and nitrile groups have a synergistic effect in the H₂S environment.

本研究研究了丁腈橡胶（NBR）在H ₂ S中的腐蚀试验。丁二烯橡胶（BR）和氢化丁腈橡胶（HNBR）用于模拟NBR中1,4-聚丁二烯和聚丙烯腈的结构单元。红外光谱，CHNS元素分析和XPS的表征可能表明，当双键和腈基共存时，NBR与H ₂ S的反应性最高，单硫和二硫键的交联出现在橡胶内部。但是，BR和HNBR的反应性降低，并且当两者分离时均未产生交联。因此，双键和腈基在H ₂ S环境中具有协同作用。
