| abstract |
【Task】 It is an object of the present invention to provide a porous film having an excellent air permeability that contributes to electrical performance and having an important shutdown characteristic in terms of ensuring safety. [Solution] The main component of the present invention is a poly-4-methyl-1-pentene polymer resin composition in which at least one peak loss tangent temperature measured by dynamic viscoelasticity measurement at a frequency of 10 Hz is between −100 to 20 ° C. A component in which the poly-4-methyl-1-pentene polymer resin composition is a poly-4-methyl-1-pentene polymer, and as a soft component, a vinyl aromatic compound and A porous film characterized in that it is a resin composition comprising a copolymer with a conjugated diene or a component that is a hydrogenated derivative thereof, and is stretched in at least one direction. [Selection figure] None |
