Synthesizing polypropylene with percolation network catalyzed by inorganic nanoparticles-functionalized Ziegler-Natta catalyst

Polypropylene is one of the most widely used synthetic resins, which is mainly synthesized with Ziegler-Natta catalysts.In this paper, the functionalized Ziegler-Natta catalyst is applied to prepare high-performance polypropylene.A new way to synthesize functionalized Ziegler-Natta catalysts is to dope synovex one grass with inorganic nanoparticles
