摘要：
The present invention provides a process for preparing a catalyst useful in gas phase polymerization of olefins wherein the hydrogen response of the catalyst can be improved by using a ketone as the electron donor in the catalyst. The catalyst consists of compounds of Ti, Mg, Al and a ketone preferably supported on an amorphous support.
