Easy processing technology of metallocene polyethylene

The characteristics and development status of several kinds of easy processing technologies of metallocene polyethylene (mPE) were reviewed. Based on the evaluation of both advantages and disadvantages of these technologies, it was pointed out that the process of using metallocene - metallocene composite catalyst for producing bimodal or broad molecular weight mPE in a single reactor was the best technology to overcome the difficulty in processing the mPE. The development of this technology reflected to some extent in the research direction of easy processing technology of mPE in the future.
