摘　　要：阐述了丁腈橡胶NBR2 40S聚合过程中 ,通过改进其原有的乳化体系 ,改善了胶乳的稳定性 ,减轻了设备堵挂 ,胶乳凝聚过程中胶粒流失减少 ,污水COD值明显降低 ,达到了长周期稳定运行及提高产品质量的目的。The polymerization of NBR240S was studied in the paper,the stability during NBR240S production and reactor-sticking have been improved by regulated its emulsifier system .Many problems during coagulation suck as serious loss of latex and exceeding of the waste waters COD have been resolved. The NBR plant could run in a long period steadily and the NBR quality could be improved.
