These intermediates were then amidated with selected aminobenzene sulfonic acids. Materials produced in this process were used as biocompatible materials and in drug delivery devices. 

Polymeric carbon nanocomposites are often functionalized with matrix polymers. An example is the functionalization of SWNTs and MWNTs with poly(vinyl alcohol) using a carbodiimide mediated esterification reaction. Also, poly(ethylene-co-vinyl alcohol) is used for this purpose to produce DMSO soluble functionalized SWNTs. In a similar manner poly(m-aminobenzene sulfonic acid) is covalently bonded to SWNTs to form water soluble graft copolymers. ... 

The first is the quite contemporary study93 for the isomeric o-, m- and p-aminobenzene-sulfonic acids. The spread of enthalpies of formation, ca 53 k.lrnol, is somewhat larger than we might have expected. However, in that these species are probably the zwitterionic NII3 1 (VJUSOt, comparisons with other species such as the uncharged benzenesulfonic acid are thwarted.

For the detection of inorganic ions, such as Cd, Wang et al. have proposed electropolymerization of p-aminobenzene sulfonic acid [p-ABSA] [113], First, GO is electrochemically reduced to RGO and simultaneously deposited at a constant potential onto a GCE surface. Electrodeposition of poly-ABSA was then carried out voltammetrically in the presence of RGO and the composite film was used for SWASV detection of Cd. Therefore, tin (replacing bismuth or mercury] was electrodeposited on top of the poly(p-ABSA] layer. The composite electrode showed good stripping performance for the analysis of Cd, wider potential window compared to bare GCE and GCE covered with only Sn, and gave a linear response from 1.0 to 70.0 gg L with a detection limit of 0.05 gg L-i.

Electrochemical homopolymerization of poly(aniline-N-alkylsulfonates) (alkyl = propyl, butyl and pentyl) in acetonitrile containing 0.1 M NaC104 and 5 % (v/v) 0.3 M HCIO4 was carried out by Rhee et al. [144]. The polymers were prepared on a platinum electrode by cyclic voltammetry (0.0 to 1.0 V vs Ag/AgCl) or potentiostatic techniques (1.0 V). These polymers were found to form liquid crystalline solutions in water. The conductivity of poly(aniline-N-propanesulfonic acid) and poly(aniline-N-butanesulfonic acid) was reportly 9 x 10 and 6 x 10 S/cm, respectively. Electrochemical polymerization of orthanilic acid, metanilic acid and sulfonic acid and their copolymerization with aniline in dimethyl sulfoxide containing tetrabutyl ammonium perchlorate were carried out by Sahin et al. [145]. These polymers and copolymers were found to be soluble in water, dimethyl sulfoxide and N-methylpyrrolidinone. The conductivity of orthanilic acid, metanilic acid and sulfonic acid was reportly 0.052,0.087 and 0.009 S/cm, respectively. The conductivity of copolymers for these three isomers of aminobenzene-sulfonic acid was reported as 0.094, 0.26 and 0.033 S/cm, respectively. Sahin et al. [146] have also prepared the copolymers of these three isomers with aniline in acetonitrile containing fluorosulfonic acid (FSO3H). The copolymers were found to be soluble in water, dimethyl sulfoxide and N-methylpyrrolidinone.
