titleOfInvention |
Polymerization process using a metallocene catalyst system |
abstract |
Provided is a process for polymerizing olefins in the presence of a metallocene catalyst compound having at least one fluoride or fluorine containing leaving group. More particularly, the present invention is directed to a process and catalyst composition having improved reactor performance, reducing or eliminating the need for anti-fouling additives to the catalyst composition and/or the reactor. In one embodiment, the invention is a process of polymerizing olefins comprising contacting ethylene and at least one comonomer with a supported catalyst system comprising a metallocene catalyst compound, the metallocene catalyst compound comprising at least one fluoride ion or fluorine containing leaving group; and wherein the supported catalyst system comprises an inorganic oxide support having an average particle size of from 35 μm or less and a pore volume of from 1 to 2 cm 3 /g. The polymer product resulting therefrom is, in one embodiment, a copolymer having a density in the range of from 0.910 g/cm 3 to 0.940 g/cm 3 ; a molecular weight distribution of from 1.8 to 4; and an I 2 of from 0.1 dg/min to 10 dg/min and is suitable for such articles as films. |
