It has showed that the feeding speed of mixed monomers, temperature for polymerization and the dosage of initiator are main factors controlling the molecular weight.
结果表明，单体加入速度、聚合温度及引发剂用量是决定聚合物分子量的主要因素。

A new kind of combined impeller was presented based on the special requirement of polymerization and its mixed property was studied.
根据聚合反应的特定工艺过程要求，提出了一种新型搅拌桨，对其混合性能进行了研究并与常规桨型进行对比。
