| Abstract: | Branched polyethylene has been prepared by using asymmetric metallocene and MAO catalytic system. By changing the conditions of polymerization, such as temperature, catalyst concentration and the ratio of c (Al)/c ( Zr) , the influence on catalytic activity and polymerization kinetic curve has been revealed. The probable mechanism for forming the branched polyethylene is also discussed. |

| Keywords: | metallocene ethylene homopolymerization branched polyethylene polymerization kinetics |
