Supported catalysts of olefin polymerization were prepared by interacting magnesium alkyls with chlorinated agents, and electron donors.
由烷基镁、氯化试剂及电子给予体制备了烯烃聚合载体催化剂。
It was found that introducing electron donating groups, such as alkyls, weaken the electron accepting ability of C60 and make its first reduction wave shifted to more negative position.
