| Abstract: | The reasons for yielding fine powder in propylene liquid phase bulk polymerization by Sphe- ripol loop process was analyzed, and the measures to reduce the fine powder was suggested. The results showed that controlling the activity,partiele size and its distribution of the catalyst, as well as the pre - contact time and propylene conversion in pre- polymerization were the key factors to reduce powder. |
