POLYOLEFIN COMPOSITION, ITS PRODUCTION METHOD, AND A BATTERY SEPARATOR MADE THEREFROM |
摘要 |
<p>The invention relates to a polyolefin composition. The polyolefin composition can be in the form of a multi-layer, microporous polyolefin membrane comprising a first microporous layer containing 7% or less by mass of ultra-high-molecular-weight polyethylene having a weight-average molecular weight of 1 x 106 or more, and having a structure in which a pore size distribution curve obtained by mercury intrusion porosimetry has at least two peaks, and a second microporous layer containing 8% or more by mass of the ultra-high-molecular-weight polyethylene.</p> |
