摘　　要：烷氧基硅烷是外给电子体的常用种类,其作为齐格勒-纳塔催化体系的重要组分,能够调节烯烃聚合物的等规度、分子量分布、熔融指数等各种性能。近年来,烷氧基硅烷类外给电子的作用机理以及发展近况是本领域的热点。本文在检索分析了大量国内外专利文献的基础上,对烷氧基硅烷外给电子体相关专利技术进行梳理和分析,并对国内该领域主要申请人的相关专利重点进行综述。Alkoxysilane is a common type of external electron donor, which can regulate the isotacticity, molecular weight distribution and melt index of olefin polymer as an important component of Ziegler-Natta catalytic system. In recent years, the mechanism and development of alkoxysilane external electron donors are hotspots in this field. Through the retrieval of hundreds of domestic and foreign patent literature related to alkoxysilane external electron donors, the related patented technologies of alkoxysilane external electron donors were summarized and the relevant patent priorities of the main applicants in this field were presented.
