Publication number: 20030229188Abstract: A high-temperature solution process for making polyolefins is disclosed. Olefins polymerize at greater than about 130° C. in the presence of an activator and an organometallic complex. The complex includes a bridged indenoindolyl ligand. One part of the ligand is a second indenoindolyl group or a polymerization-stable, cyclopentadienyl-like group having an extended pi-electron system. Because the catalysts activate quickly and thoroughly, even with low levels of an alumoxane, the invention provides an efficient way to make high-molecular-weight (Mw>100K) polyolefins.Type: ApplicationFiled: May 31, 2002Publication date: December 11, 2003Inventors: Sandor Nagy, Barbara M.
