TL;DR: A sulfonated diamine monomer was successfully synthesized by direct sulfonation of a commercially available diamine, 4,4‘-diaminodiphenyl ether (ODA), using fuming sulfuric acid as the sulfonating reagent.
Journal ArticleDOI
Novel sulfonated polyimides as polyelectrolytes for fuel cell application. 2. Synthesis and proton conductivity of polyimides from 9,9-bis(4-aminophenyl)fluorene-2,7-disulfonic acid
TL;DR: In this paper, a new sulfonated diamine monomer, 9,9-bis(4-aminophenyl)fluorene-2,7-disulfonic acid (BAPFDS), was synthesized by direct sulfonation of the parent diamine using fuming sulfuric acid as the sulfonating reagent.
Journal ArticleDOI
Hyperbranched Polyimides for Gas Separation Applications. 1. Synthesis and Characterization
TL;DR: A series of wholly aromatic hyperbranched polyimides were successfully prepared by condensation polymerization of a triamine monomer, tris(4-aminophenyl)amine (TAPA), and a series of commercially available dianhydride monomers such as 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropane (6FDA), 3,3-diphenylsulfonetetracarboxylic dienhydride (DSDA), and pyromell
Journal ArticleDOI
Synthesis and properties of highly sulfonated proton conducting polyimides from bis(3-sulfopropoxy)benzidine diamines
TL;DR: In this article, two novel sulfonated diamine isomers, 2,2′-bis(3-sulfopropoxy)benzidine (2,2''-BSPB) and 3,3''-bis (3-SPSPoxy)Benzidine(3, 3''-SSPB), were successfully synthesized and showed high proton conductivities with sulfonic acid groups in the side chains.
Journal ArticleDOI
Synthesis, water stability and proton conductivity of novel sulfonated polyimides from 4,4′-bis(4-aminophenoxy)biphenyl-3,3′-disulfonic acid
TL;DR: In this article, a sulfonated diamine monomer, 4,4′-bis(4-aminophenoxy)biphenyl-3,3′-disulfonic acid (BAPBDS) with the high basisity and flexible structure was synthesized by direct sulfonation of BAPB.
