摘要:: 摘要：通过将外给电子体Donor-C和Donor-D在Spherizone工艺技术聚丙烯装置上的应用，考

察了不同的外给电子体对聚合反应及产品性能的影响，结果表明在生产均聚牌号时Donor-D

作为助催化剂的使用，主催化剂活性平均提高了25%~30%、产品的弯曲模量提高20%~30%、

拉伸屈服应力提高10%，改善产品刚性性能，可有效拓宽产品应用范围和领域。

Abstract: Through the application of Donor-C and Donor-D in Spherizone polypropylene plant, the effects of different external

electron donors on polymerization and product performance were investigated. The results show that when donor-D is used as a

co-catalyst in the production of homopolymerization, the activity of the main catalyst is increased by 25%~30% on average, the

bending modulus of the product is increased by 20%~30%, the tensile yield stress is increased by 10%, and the rigidity of the

product is improved, which can effectively expand the application range and field of the product.
