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.

Key words: METALLOCENES, POLYETHYLENE, ZIRCONIUM CHLORIDE, ETHYLENE
