Catalyst system for high activity and stereoselectivity in the homopolymerization and copolymerization of olefins
MetadataShow full item record
The present invention is directed to a novel composition, and to a method of making the composition, the composition being useful in catalyst systems for the homopolymerization and/or copolymerization of olefins, wherein such catalyst systems display a higher level of activity and stereoselectivity than previously reported. The present invention is also directed to novel polymeric compositions made with such catalyst systems, such as a novel syndiotactic polypropylene that melts at temperatures higher than previously reported.
