摘要
目前,在烯烃催化聚合领域的最大的挑战之一是极性单体的催化聚合,或者极性单体于非极性烯烃的共聚。极性单体,像丙烯酸甲酯、乙烯醚等,能极大的改进烯烃聚合物的物理以及化学性质。通过金属催化剂聚合极性单体非常困难,因为极性单体及其容易毒化催化剂。在本次报告中,我会讨论本课题组近期在设计与制备新型烯烃聚合催化剂中的一些工作。通过对配体的调节,我们可以极大的提高这催化剂体系的活性、热稳定性。并且我们可以极大的提高所制备的聚乙烯以及共聚物的分子量、降低其支化度,从而得到半结晶型的固体材料。同时,本次报告也会涉及我们在设计并且制备其它新型的烯烃聚合催化剂体系中,以及新型的烯烃聚合调控手段方面的一些工作[1-5]。
Currently,one of the biggest challenges in the field of olefin polymerization is the catalytic polymerization of polar monomers or their copolymerization with non-polar olefins.Polar monomers such as methyl acrylate or vinyl ethers could greatly enhance the physical and chemical properties of the polyolefin materials.However,it is extremely difficult to do this because the polar monomers can easily poison the metal catalysts.In this presentation,I will discuss some of our recent works on the design and synthesis of new olefin polymerization catalysts.It is possible to improve the activity and stability of these catalysts through ligand modifications.We were able to greatly increase the polymer molecular weight and decrease the polymer branching density,leading to semicrystalline solid materials.In the second part of the talk,the new techniques to modulate the olefin polymerization and copolymerization process will be discussed.For example,the metal-metal cooperativity effect from a dinuclear catalyst,the redox controlled olefin polymerization strategy will be described.
