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