HIGH MOLECULAR WEIGHT POLYPROPYLENE PROCESS

摘要

A propylene polymerization process is disclosed. The process uses a fluorenyl-indenoindolyl catalyst precursor in the presence of an activator to obtain high molecular weight polypropylene with low degrees of isotacticity and syndiotacticity. In particular, the polypropylene has tacticity such that mmmm is 0-20% and rrrr is 0-60%.
