摘要： Methods for making olefin polymerization catalysts and methods for making polymers using the catalysts are provided. The method for making the catalyst can include combining one or more supports with one or more magnesium-containing compounds under reaction conditions to form a first reacted product. One or more chlorinating compounds selected from the group consisting of aluminum alkyl chlorides and chloro substituted silanes can be combined with the first reacted product under reaction conditions to form a second reacted product. One or more titanium-containing compounds selected from the group consisting of titanium alkoxides and titanium halides can be combined with the second reacted product under reaction conditions to form a catalyst.

摘要： Polymerization process control methods for making polyethylene are provided. The process control methods include performing a polymerization reaction in a polymerization reactor to produce the polyethylene, where ethylene, and optionally one or more comonomers, in the polymerization reaction is catalyzed by an electron donor-free Ziegler-Natta catalyst and an alkyl aluminum co-catalyst. A melt flow ratio (I21/I2) of the polyethylene removed from the polymerization reactor is measured and an amount of long chain branching (LCB) of the polyethylene from the polymerization reactor is controlled by adjusting a weight concentration of the alkyl aluminum co-catalyst present in the polymerization reactor. In addition, an electron donor-free Ziegler-Natta catalyst productivity of the polyethylene being produced in the polymerization reactor is measured from which the amount of LCB of the polyethylene from the polymerization reactor is determined using the measured electron donor-free Ziegler-Natta catalyst productivity and a predetermined relationship between the electron donor-free Ziegler-Natta catalyst productivity and the LCB.
