<p>A separation membrane comprising a resin being constituted of the repeating unit represented by the general formula (I) and having a number average molecular weight of not less than 1 x 10<3> in polystyrene equivalent: <CHEM> where R1 denotes an alkyl group of 1 - 20 carbons, a fluoroalkyl group of 1 - 20 carbons, or a group represented by the general formula: -(-X-)m-(SiR2R3-)n-R4, or -(-X-)m-(-SiR2R3O-)n-SiR4R5R6 (wherein X is an alkylene group of 1 - 8 carbons or a phenylene group of 6 - 12 carbons; m is 0 or 1; n is an integer of 1 - 20; R2, R3, R4, R5, and R6 are respectively a group, having 1 - 8 cabons, selected from an alkyl group, a cycloalkyl group, a phenyl group, an alkoxyl group, and a fluoroalkyl group, and may be the same with or different from each other).</p> |
