Microporous membrane of ultra-high molecular weight alpha-olefin polymer |
| abstract |
A micro-porous membrane of ultra-high-molecular-weight alpha-olefin polymer having a weight-average molecular weight greater than 5 x 10<sup>5</sup>, the micro-porous membrane having through holes 0.01 to 1 micrometer in average pore size, with a void ratio from 30 to 90% and being orientated such that the linear draw ratio in one axis is greater than two and the areal draw ratio is greater than ten. The micro-porous membrane is obtained by forming a gel-like object from a solution of an alpha-olefin polymer having a weight-average molecular weight greater than 5 x 10<sup>6</sup>, removing at least 10 wt% of the solvent contained in the gel-like object so that the gel like object contains 10 to 90 wt% of alpha-olefin polymer, orientating the gel-like object at a temperature lower than that which is 10°C above the melting point of the alpha-olefin polymer, and removing the residual solvent from the orientated product. A film is produced from the orientated product by pressing the orientated product at a temperature lower than that of the melting point of the alpha-olefin polymer. |
