Abstract
The invention provides for highly crystalline syndiotactic polypropylene comprising a high percentage of racemic (r) dyads. The high crystallinity may be due to the polymerization mechanism of metallocene catalysts of a particular structure which appear to produce syndiotactic polypropylene of a new microstructure.
