SUPPORTED ANTISTATIC POLYMERIZATION CATALYSTS |
摘要 |
<p>The use of high activity "Single Site" polymerization catalysts often causes the fouling of polymerization reactors. The problem is particularly acute with gas phase polymerizations. While not wishing to be bound by theory it is believed that the fouling is initiated by the buildup of static charges in the reactor. The use of anti-static agents mitigates this problem, but typical antistatic agents contain polar species, which can deactivate the polymerization catalyst. We have now discovered that the use of a porous metal oxide support allows large levels of a selected antistatic agent to be used in a manner that reduces static/fouling problems in highly active polymerization catalysts.</p> |
