| abstract |
The present invention comprises a step in which a polyolefin and a polyolefin elastomer are first charged into an extruder and then a carbon-carbon double bond group-containing alkoxysilane, an initiator, and a cross-linking catalyst are secondarily charged. The present invention relates to a method for producing a separation membrane and a separation membrane. According to the present invention, it is possible to provide a method for producing a crosslinked polyolefin separation membrane having a high meltdown temperature and a low shutdown temperature at the same time, and a separation membrane produced by the method. |
