Abstract: Propylene heterogeneous copolymerization is an important process to improve the performance of polypropylene. The recent progress of the catalysts for propylene heterogeneous copolymerization is reviewed in this paper. The main processes to produce propylene heterogeneous copolymer by in-situ technology are introduced. It is suggested that the effective combination of Ziegler-Natta catalyst and metallocene catalyst to produce propylene heterogeneous copolymer is the future trend of research and development.
