介绍了聚丙烯（PP）树脂中灰分的组成，并分析了影响PP树脂中灰分含量的主要因素。从催化剂和聚合工艺两方面综述了世界上各大公司开发的直接在反应器内制备高纯PP的技术进展，并详细分析了各技术的优缺点及工业化前景。目前，各大公司生产高纯PP主要采用Ziegler-Natta催化剂，内给电子体包括多元羧酸酯类、琥珀酸酯类、醚类、二醇酯类以及含有可取代的亚苯基芳香族二酯类化合物，聚合工艺包括气相工艺、液相工艺以及超临界技术，且大多对助催化剂（即有机铝化合物）的用量进行了严格限定。

The ash composition in polypropylene(PP)resin was introduced and the major factors affecting ash content in PP resin were analyzed. The technological progresses of high purity PP resin produced directly in the polymerization reactor developed by many big companies around the world were summarized from the catalysts and polymerization processes. The advantages and disadvantages, industrialization prospects of differen t technologies were analyzed in detail. At present, the main cata-lysts for high purity PP employed by many big companies were Ziegler-Natta catalysts and the internal donors included polycarboxylic acid ester, succinate, ether, diolester and a substituted phenylene aro-matic diester. The polymerization processes were gas phase polymerization, liquid phase polymeriza-tion and supercritical polymerization. Moreover, the cocatalyst(that is, the organo-aluminium com-pound) dosage was limited strictly in these polymerization processes.
