According to the special requirements of polymerization process, a new type of combined impeller is presented and its mixing property is studied comparing with the general impeller by experiments.
The polymerization kinetics of the combined catalyst showed that its initial polymerization rate was fast and the life was longer.
聚合动力学试验表明，该复配催化剂的引发较快、寿命较长。
