摘　　要：针对茂金属催化剂负载化过程中所产生的废溶剂开展了相关的回收工艺研究。结果表明:MAO清液可以完全回用于催化剂的负载工艺中,对聚合活性及聚合物性能均无影响;废己烷可以通过沸点的差异得到回收,废己烷总量的95%得到回收利用,总量的5%作为废液排出。该工艺具备了清洁工艺的特点,大大降低了对环境的污染。The recovery and reuse of waste solvent from the loading process of metallocene catalyst were studied.The results showed that the recovered MAO solvent could be reused in loading process of metallocene catalyst.This loading catalyst had no influence on polymerization activity and properties of polymer.The waste hexane could be recovered by the difference of boiling points.About 95% of waste hexane was recovered and reused.The process had the character of clean process and reduced the pollution.
