Polypropylene: 44 Years Young! The Challenge for the 21st Century as high as those obtained with previous catalysts. The achievement of a better control of the polymer structure has resulted in an increased capability to tailor the products according to the performance requirements, both in the conversion technologies and in the application life cycle, as well as to extend their application to new market areas.

Expanding the Scope of Metallocene Catalysis: Beyond Indenyl and Fluorenyl DerivativesGroup 4 metallocenes with bridged and substituted Ind and Cp/Flu ligands have produced high-molecular-weight isotactic (I-PP), syndiotactic (S-PP), atactic (A-PP) and hemi-isotactic (HIT-PP) (Scheme 1) polypropylenes..
