The development history of metallocene catalyst and the research progress of supported metallocene catalyst were summarized. The applications of metallocene catalyst to polyethylene, polypropylene,polystyrene,cyclic olefin copolymer and synthetic lubricant additive,etc. were analyzed. The application of metallocene catalyst to the industrial development of high value-added polyolefin would be accelerated with further researches on organic carrier properties and supported methods. The mechanical properties of linear low density polyethylene which was prepared with metallocene catalyst were better than those of normal linear low density polyethylene. And the product quality was comparable with ethylene-1-octene copolymer. The controlled polymerization of polypropylene alloys was realized by means of metallocene catalyst. The research and development in China should be focused on the supported metallocene catalyst to reduce the production cost of metallocene olefins.
