Abstract
A method for manufacturing a crosslinked polyolefin separator and a separator are provided. The method includes putting a polyolefin and a polyolefin elastomer into an extruder first, and putting an alkoxy silane containing a carbon-carbon double bond functional group, an initiator and a crosslinking catalyst to form the separator. The crosslinked polyolefin separator has high meltdown temperature and low shutdown temperature.
