Abstract: The present invention provides a catalyst composition and process for preparing olefin polymers. The catalyst composition includes a metallocene catalyst or a single-site catalyst, a mesoporous molecular sieve, and an aluminum-containing cocatalyst such as MAO. The cocatalyst is present in an amount such that the molar ratio of aluminum content in cocatalyst to the metal content in metallocene is from 0 to 200. When the catalyst composition is used for preparing polyolefins, the MAO amount can be decreased; thus, the production costs are greatly reduced.

Abstract: The present invention provides a metallocene catalyst supported on a molecular seive having nulltubules-within-a-tubulenull morphology. When the metallocene catalyst is used for preparing polyolefin, the MAO amount can be decreased to an amount such that the molar ratio of Al/Zr is below 200. Thus, production costs are greatly reduced.
