摘　　要：通过对HDC聚丙烯催化剂载体在不同条件下的脱醇试验,得到不同乙醇/氯化镁摩尔比(简称醇镁比)的载体,不同醇镁比载体合成催化剂后经聚合得到聚合产物。结果表明,改变脱醇条件,可得到精确醇镁比的载体,而经脱醇后的载体合成的催化剂的活性提高,氢调敏感性明显改善。HDC polypropylene catalyst carrier with different molar ratio of alcohol and magnesium are obtained after the dealcoholization under changed operating conditions.The HDC catalyst prepared by carrier with different alcohol/ magnesium ratio is used to catalyze the polymerization of propylene.The results show that accurate ratio of alcohol and magnesium can be obtained by changing the condition of dealcoholization.And the catalytic activity can be improved after dealcoholization.
