摘　　要：针对顺丁橡胶装置聚合丁二烯转化率偏低的问题,阐述影响镍系顺丁橡胶聚合反应及聚合丁二烯转化率的主要因素,并提出了提高聚合丁二烯转化率的解决方案。通过长期不断调整优化摸索,确定了调整催化剂铝镍陈化稀释油的加入量及优化回收单元脱水塔和丁二烯塔的工艺操作条件的优化调整方案,有效解决了聚合丁二烯转化率偏低的问题,使聚合丁二烯转化率由不足80%稳定提高至84%以上。The background of the low conversion rate of butadiene in polymerization course of cis-polybutadiene rubber was introduced.Main factors affecting the polymerization reaction and the conversion rate of the butadiene in polymerization of nickel-based cis-polybutadiene were described,and the solution to raise conversion rate of the butadiene was given.
