摘要：
The invention relates to microporous membranes having high meltdown temperature, low shutdown temperature, and resistance to heat shrinkage at elevated temperature. The membranes can be produced by stretching a sheet comprising polymethylpentene, polyethylene, and diluent, and then removing the diluent. The membranes can be used as battery separator film in, e.g., lithium ion batteries.
