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.
