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 103 in polystyrene equivalent:
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, Rs, 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).
一种分离膜,由通式(I)所代表的重复单元构成的树脂组成,其聚苯乙烯当量的平均分子量不小于 1 x 103:
其中 R1 表示 1 - 20 个碳原子的烷基、1 - 20 个碳原子的氟烷基或由通式表示的基团:-(-X-)m-(SiR2R3-)n-R4,或-(-X-)m-(-SiR2R3O-)n-SiR4R5R6(其中 X 为 1 - 8 碳原子的亚烷基或 6 - 12 碳原子的亚苯基;m 为 0 或 1;n 为 1 - 20 的整数;R2、R3、R4、Rs 和 R6 分别是具有 1 - 8 个空位的基团,选自烷基、环烷基、苯基、烷氧基和氟烷基,它们之间可以相同或不同)。
