Bridge Substituents and Syndiotactic Polypropylene Molecular Weight

3 Bridge Substituents and Syndiotactic Polypropylene Molecular Weight 

Two different views of the molecular structure of 6 (and 7) are portrayed in Fig. 13. From both a molecular symmetry point of view and from solid structural characteristics (bond distances and bond angles) point of view, complexes 6 and 7 appear almost indistinguishable from 1 and 2 [20]. It was, therefore, expected that
