How does the presence of amines affect the productivity of polypropylene polymerization in industrial settings?

Label:chem

Topic
In industrial polypropylene production, trace amounts of impurities like amines can significantly impact the efficiency of the polymerization process. Understanding their effects is crucial for optimizing industrial processes.
Answer
The presence of DMA and DEA in polypropylene polymerization leads to substantial productivity losses. Specifically, 140 ppm of DMA and 170 ppm of DEA caused productivity losses of 19.6% and 20%, respectively. This highlights the need for stringent control of amine impurities in industrial polymerization processes to maintain high catalyst efficiency.
