4-Chloro-diphenyl sulfone

Figure 8.12 TEM photographs of triblock copolymers dispersed in a DGEBA-diamine epoxy network. The triblock copolymer is polystyrene-b-polybuta-diene-b-poly(methyl methacrylate), and the epoxy hardener is (a) -methylene bis [3-chloro-2,6 diethylaniline], MCDEA, and (b) 4,4 -diamino diphenyl sulfone, DDS. In the case of the epoxy system based on MCDEA, the PMMA block is miscible up to the end of the epoxy reaction. In the case of the epoxy system based on DDS, the PMMA block phase-separates during reaction. (From LMM Library.)... 

It was also discovered that diphenyl sulfone 223, by prolonged heating with chlorosulfonic acid (six equivalents) at 90 °C, gave a low yield of the 3-sulfonyl chloride 225 (Equation 71). Treatment of ethyl phenylsulfone and its p-chloro derivative with the reagent both yield the corresponding 3-sulfonyl chlorides so that sulfonation occurs, as expected, in the meta position relative to the sulfonyl group. Di-p-xylylsulfone reacts with chlorosulfonic acid (10 parts, 150-160 °C) to yield the 3,3 -disulfonyl chloride. ... 

Diphenyl-1,10-phenanthroline and 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline give disulfonic acids on reaction with chloro-sulfonic acid at 25°. The position of substitution was not established, but presumably it occurs in the two phenyl rings.281 An improved method of sulfonation utilizes hot fuming sulfuric acid.282...

Finally, we mention some other attempts that have been directed toward the preparation of copolymers poly(aniline-co-o//w-toluidine) [732, 733], poly(aniline-cothiophene) [734], poly(aniline-co-aniline with sulfonate, alkylsulfonate, carboxy-late, chloro and fluoro groups) [735], poly(aniline-co-/7-phenylene diamine) [737], poly(aniline-co-w-phenylenediamine) [736, 738], poly(aniline-co-diphenyl-amine) [164,360,739], poly(aniline-co-dithioaniline [740], as well as copolymers of diphenylamine and anthranilic acid [361] or benzidine [349], iV-vinylcarbazole and thienylpyrrole and terthiophenes [618], and aniline with aminonaphthalenesul-fonates [243]. Several other works that describe copolymers can be found among...
