PROCESS FOR THE PREPARATION OF A CATALYTIC COMPOSITION FOR THE POLYMERIZATION OF ALPHA-OLEFINS, CATALYTIC COMPOSITION OBTAINED THEREOF AND POLYMERIZATION PROCESS USING THEREOF |
摘要 |
<p>The process comprises contacting a catalyst with an alpha -olefin under polymerization conditions in a diluent to form a composition. The catalyst comprises a Group IV-VI transition metal complex with an optionally substituted cyclopentadiene ligand, an activator and a support. A process (A) for producing a catalyst composition for polymerizing alpha -olefins comprises contacting a catalyst with an alpha -olefin under polymerization conditions in a diluent to form a composition comprising 0.01-50 g polyolefin per gram of catalyst. The catalyst comprises: (i) a Group IV-VI transition metal complex with an optionally substituted cyclopentadiene ligand; (ii) an activator selected from aluminoxanes and ionizing agents; and (iii) a support comprising porous polyolefin particles. The diluent has a kinematic viscosity of 3-3000 cS at 20 degrees C. Independent claims are also included for the following: (1) a catalyst composition produced by a process (A) as above; and (2) a process (B) for homo- or co-polymerizing alpha -olefins using a catalyst composition as above.</p> |
