本文报道以[Me~2C(Cp)(Ind)]ZrCl~2为主催化剂，MAO为助催化剂，仅以乙烯为单体制备支化聚乙烯的结果。

关键词: 金属茂络合物, 聚乙烯, 氯化锆, 乙烯

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
