MANUFACTURE OF STEREOREGULAR POLYMERS

摘要

PURPOSE: A stereo-regular polymer is provided to include an easiness of manufacturing a catalyst, an elimination of a catalyst inactivation by a supporter, a removal of an inorganic supporting material remnant in the product, and an absence of oil from the supported catalyst slurry. CONSTITUTION: The present invention teaches the use of particular soluble metallocene catalysts to produce stereo-regular polymers in gas phase polymerizations wherein the catalysts are fed into a particle lean zone in the reactor. The metallocenes catalysts are bridged bis-(substituted indenyl) compounds.
