Abstract
AbstractWell defined AB and BAB type poly[styrene(ST)‐b‐4‐vinylpyridine(4VP)]s were prepared by anionic living polymerization in tetrahydrofuran (THF) at −78°C. Casting AB and BAB type poly(ST‐b‐4VP)s with a composition of about 50 mol% PST from 1,1,2‐trichloroethane (TCE) produced specimens with lamellar microdomain structures. Quaternization of P4VP and sulfonation of PST domains (lamellar and spherical structures), accompanied by each domain fixing, were carried out under various reaction conditions. The piezodialysis of the prepared charge mosaic membrane with its lamellar microdomain structure was measured from a sodium chloride (NaCl) aqueous solution. The results are discussed in some detail.
