Abstract: PURPOSE: A polymer membrane prepared with a polymer material introduced a crosslinked structure in an inside polymer and a siloxane group in main chains is provided which has excellent processability, mechanical strength and separation performance. CONSTITUTION: Siloxane diamine of formula 1 and one or two or more dicarboxylic acid derivatives selected from diacylchloride, disulfonylchloride, diacid, dianhydride and monoacid-monoanhydride are polycondensated and crosslinked to produce a polymer separation membrane containing crosslinked organopolysiloxane. The polymer separation membrane exhibits excellent separation performance by applying to general membrane separation process such as gas separation and permeation evaporation.

Abstract: PURPOSE: A polymer containing perfluoride alkyl-siloxane group and a separation membrane using the polymer are provided, to improve the separation efficiency of the separation membrane. CONSTITUTION: The polymer containing perfluoride alkyl-siloxane group is obtained by condensation polymerizing perfluoride alkyl-containing diamine represented by the formula 1; siloxane diamine represented by the formula 5; and one or more dicarboxylic acid derivatives selected from diacyl chloride, dianhydride, disulfonyl chloride, diacid and monoacid-monoanhydride. The equivalence of the dicarboxylic acid derivatives is equal to that of the two kinds of diamines. In the formula 1, Rf is represented by C(W1W2W3)(CF3)n(X)m(Y)-; W1, W2 and W3 represent H, F, Cl or CF3; X represents CONR or SO2NR (wherein R is H or an alkyl group of C1-C5); Y represents an alkylene group of C1-C10 substituted with OH or OCOCH3 or unsubstituted; n is an integer of 2-20; and m is 0 or 1, and in the formula 5, m is an integer of 2-95. The separation membrane is asymetric and is prepared by using one or two kinds of the polymer with the number mean molecular weight of 5,000-100,000.
