Abstract: Polymethylpentene could be good membrane materials because of it’s excellent properties. In this paper，the method for making polymethylpentene membrane is reviewed，especially the principle，the process，the effects，and the properties of the membrane gained. Phase separation (nonsolvent induced phase separation，spreading solution on water surface and so on)，melt stretch，thermally induced phase separation are included.
