Polyolefin synthetized by olefin monomers, as the polymer materials of the highest production and consumption, have a lot of advantages such as cheap price, recoverability, various performance and easiness to modification. Pervaporation as the newly-developing chemical engineering technology is playing an increasingly important role in term of its environmental friendliness and low energy consumption. The further expanding functionalization and utilization in membrane pervaporation separation of polyolefin like polyethylene and polypropylene, which are mainly applied in plastic packaging film, will not only make use of technical superiority of present production line but also add the value greatly. Through the review of the laboratory research for pervaporation separation of polyolefin membrane, the development and prospect of the study is also proposed.AcknowledgementsThe authors greatly appreciate the financial supports of the Major State Basic Research Program of China (2009CB623404), National High Technology Research and Development Program of China (No. 2012AA03A607), National Natural Science Foundation of China (21176135, 21206001), Beijing Natural Science Foundation(2132010).
