POLYMER CONTAINING PERFLUOROALKYL AND POLYMER SEPARATION MEMBRANE USING THE SAME

摘要

PURPOSE: Provided is a polymer separation membrane, which has an excellent separation capability, and is appropriate to a separation membrane for separating gas, a hydrophobic separation membrane for separating permeation evaporation, an ultrafiltration separation membrane, a hydrophobic separation membrane for separating reverse osmosis. CONSTITUTION: The perfluoroalkyl-contained polymer is obtained by polycondensation of perfluoroalkyl-contained diamine(formula 1) and dicarboxylic acid derivatives comprising at least one or more selected from the group consisting of diacylchloride, dianhydride, disulfonylchloride, diacid and monoacid-monoanhydride. In the formula 1, Rf represents C(W1W2W3)(CF2)n(X1)m(X2)-, wherein, W1, W2 and W3 represent each H, F, Cl or CF3; X1 is CONR or SO2NR, wherein, R is H or C1-C5 alkyl group; X2 is substituted or unsubstituted C1-C10 alkylene group with OH or OCOCH3; n is integer of 2-20; and then m is integer of 0 or 1.
