Abstract

Progress on high-performance polyolefin materials development based on functionalization of Ziegler-Natta catalysts is introduced. Ziegler-Natta catalyst/Advanced Polymerization Coagent (APC) compound strategy greatly expands the property envelop of Ziegler-Natta catalysts. Among the ongoing developments

Ziegler-Natta/

- alkenylmethyldichlorosilane functional catalyst system has shown its industrial potential in preparation of long-chainbranched/ high-melt-strength polypropylene (PP)

while Ziegler-Natta/nonconjugated

-diolefin system provides a revolutionary innovation to heterophasic polymerization of propylene

allowing preparation of PP-based thermoplastic elastomers (TPO

with increasing rubber contents). Other strategies such as Ziegler-Natta/metallocene compound catalysts and nano-supported Ziegler-Natta catalysts further boost Ziegler-Natta catalysts properties for preparation of new high-performance polyolefin materials.
