At appropriate polymerization conditions the binary catalyst system shows a good synergic effect, the polymerizationactivity is higher than any single catalyst.
在合适的聚合条件下此复式催化剂具有很好的协同作用，其催化活性比任一单一催化剂的催化活性都高。

Polymerization control is the control of polymerizationactivity and polymer Mooney viscosity, namely the production capacity and product quality control during polymerization.
聚合过程控制为聚合活性与聚合物门尼粘度的控制，即聚合过程生产能力与产品质量的控制。
