Propylene and Ethylene Polymerization Initiated with Mg-Supported Ti Catalysts : Effects of Internal Donor |
| 초록 |
The electron donor (Lewis Base) in typical Ziegler-Natta catalyst system is divided into two types: the internal donor (ID) is added in the preparation of catalyst, while the external donor (ED) is used at the polymerization process. These donors exhibit the significant effects on the polymerization behaviors in polyolefin preparation. The ZieglerNatta catalysts of various IDs exhibited the different polymerization behaviors. Without any ED (dialkoxysilane), the catalyst of aliphatic diester and diether ID gave the reasonable catalyst activity and isotacticity in propylene polymerization. In this presentation, the polymerization behaviors of various catalysts with various IDs for homopolymerization and copolymerization of propylene and ethylene were investigated. |
