Poly , disulfonate

Analysis of neutral product for active species. The di- and poly sulfonates present in AOS have been isolated from monosulfonates by column chromatography using silanized silica gel by Puschmann [109]. The content of mono-and disulfonates in the fractions obtained were determined gravimetrically. [Pg.435]

Direct copolymerization techniques have also been employed in the s)m-thesis of sulfonated poly(aryl ether ketones),i i polyimides, i 5 and poly(benzoimidazoles). The synthesis of random disulfonated biphenol poly(arylene ether sulfone) copolymers (BPSH x where x represents the percentage of disulfonated diphenylsulfone moieties in the polymer versus unsulfonated diphenylsulfone moities) (14) is shown in Scheme 3.5. [Pg.144]

These polymers show lower water uptake than the analogous sulfonated poly(arylene ether sulfone) materials, possibly suggesting some interaction between the aromatic nitrile and sulfonic acid. The phosphine oxide functional moiety could also be used as a compatibilizer with other materials. Sulfonated poly(arylene ether phosphine oxide sulfone) terpoly-mers have been prepared both with sulfonated triphenyl phosphine oxide and with triphenyl phosphine oxide with 3,3 -disulfonate-4,4 —dichlorodiphenyl sulfone as the sulfonic acid bearing monomer. Block copolymers containing phosphine oxide appear to avoid the ether—ether interchange that results when non—phosphine oxide blocks are utilized, and this is being further pursued. ... [Pg.358]

Cho et al. have recently described the synthesis of a sulfonimide containing monomer and the resulting poly (ary lene ether sulfone) copolymers. In this procedure 3,3 -disulfonate-4,4 —dichlorodiphenyl sulfone was refluxed in thionyl chloride, isolated, and then reacted with trifluoromethanesulfonamide in the presence of triethylamine to form the sulfonamide analogue monomer as shown in Figure 44. This... [Pg.367]

The base-catalyzed additions of glyoxal to formamide and methanesulfonamide afforded 1,4-diformyl- (895, 1663) and l,4-bis(methylsulfonyl) derivatives (895) of 2,3,5,6-tetrahydroxypiperazines, respectively, in addition to the corresponding A iV -disubstituted 1,2-diamino-l, 2-ethanediols (895). Salts of 2,3,5,6-tetrahydroxy-piperazine-l,4-disulfonic acid were similarly prepared by the addition of aqueous glyoxal to sulfamic acid in the presence of base (1664). Ethylene dichloride with hydrazine in ethanol gave ethylene dihydrazine, 1,4-diaminopiperazine, and poly(ethylenehydrazine) (1665). [Pg.375]

Sulfonated poly(phthalazinone ether ketone nitrile) (SPPEKN) copolymers prepared by the copolymerization of disodium 3,3 -disulfonate-4,4 -difluorobenzophenone, 2,6-difluorobenzonitrile, and 4-(4-hydroxy-phenyl)-l(2H)-phthalazinone exhibit a tensile strength higher than that of Nafion 117. The proton conductivities of the acid form of SPPEKN copolymers, with a feed ratio or sulfonated to unsulfonated monomer above 0.35, are around lO Scm at 80°C, which is close to that of Nafion 117.39... [Pg.295]

Poly(l-vinylimidazole)i2-[Os-(4,4 -dimethyl-2,2-bipyridyl)2Cl2] and poly(vi-nylpyridine)-[Os-(Ai,Ai -methylated-2,2 -biimidazole)3] were reported for their efficient capability of mediating electrons transfer between bacterial cells to electrodes. With S. oneidensis, the osmium redox polymer modified anode showed a 4-fold increase in current generation and a significant decrease in the start-up time for electrocatalysis. Using an anode modified with electropolymerized polypyrrole, a dramatie improvement in energy output was noticed in the MFCs. MFCs with a polypyrrole/ anthraquinone-2,6-disulfonic disodium salt (PPy/AQDS)-modified anode... [Pg.147]

From 2,5-bis(4-lluorophenyl)-1,3,4-oxadiazole and 2,2-bis(4-hydroxypheny)propane bisphenol A and 3, 3-disulfonate-4 4-dichloro diphenyl sulfone, a poly(aryl ether sulfone) containing 1,3,4-oxadiazole moieties was obtained [65]. From this polymer, proton exchange membranes have been fabricated. The sulfonated polyoxadiazole membranes exhibit excellent thermal, dimensional and oxidative stability, and a low methanol diffusion coefficient. Thus, these sulfonated polyoxadiazole membranes may be alternative materials for proton exchange membranes at medium to high temperature operations. [Pg.248]
