摘　　要：文中介绍了目前丙烯的低聚合成即丙烯的二聚、三聚和四聚的研究进展。丙烯二聚反应和丙烯三四聚反应研究的主要区别在于它们的目标产物不同。丙烯二聚反应主要选择性的制备特定结构丙烯二聚体,而丙烯三四聚反应则产生更高碳数的聚合物,且由于对于高碳数烯烃同分异构体分析手段的缺乏,无法对高聚物的结构具体分析从而对催化剂选择性进行有目的的调整。未来对丙烯齐聚工艺的研究方向包括进一步提高催化剂的选择性和稳定性,降低反应温度和压力,开发更高效的催化剂以及分析检测方法的同步。This paper presents the latest research progress in the low-degree polymerization of propylene,encompassing di-propylene,tri-propylene,and tetra-propylene.A key disparity between research into propylene di-polymerization and propylene tri-/tetra-polymerization lies in their respective target products:while propylene di-polymerization selectively yields specific structural propylene di-polymers,propylene tri-/tetra-polymerization generates polymers with higher carbon numbers.However,due to limitations in analytical techniques for high-carbon-number olefin isomers,it remains challenging to ascertain the precise structure of these polymers or adjust catalyst selectivity deliberately.Future directions for research into propylene oligomerization involve further enhancing catalyst selectivity and stability,reducing reaction temperatures and pressures,and developing more efficient catalytic systems.
