As one of the five general purpose synthetic resins

polypropylene (PP) has the properties of non-toxicity

tasteless

low density

high stiffness

high impact strength

and good chemical resistance. PP can be made to weave product

injection product

film

pipe

and so on

and can be used widely in the package

automobile

household electrical appliances

building materials

commodity

and so on. Catalyst technology is the core of PP technology. Polymerization process is the key of mass production of PP with low cost. Development of new product is important method for the improvement of properties of PP and expanded using range. In this paper

the latest advance of research and development of PP catalyst was summarized

especially the gas phase polymerization processes of PP with high growth rate were introduced

and the usage of PP with high performance in the high-end fields

such as automobile

medical package

pipe

film

and so on

was prospected.
