It is included that 4-5 types of active sites exist in the catalytic system and the active site produced polymer with low molecular weight is easy to be activiated while TEA is used as the cocatalyst. While TIBA, the active site produced polymer with high molecular weight and seldom active site produced polymer with low one is prone to be activiated. MAO tends to activiate the active site produced polymer with middle-level molecular weight. In TEA-TIBA catalytic system, TEA and TIBA activiate the corresponding active site and the weight of every active site gradationally varied with the change of the ratio of the two cocatalysts.
