Abstract
A process for preparing a long chain branched polypropylene in presence of two metallocene-based active catalyst systems is provided. The polypropylene obtained therefrom has new molecular architecture and improved elasticity properties. The polypropylene is further characterized by new signals in its 13C NMR spectrum.
