Kinetics and mechanism of polyphenylene formation by polyarylation with arylsulfochlorides

Kinetics and mechanism of polyphenylene formation by polyarylation with arylsulfochlorides. Rafler, Gerald; Ikladios, N. E.; Reinisch, Gerhard; Bonatz, Eckhard; Sergeev, V. A. (Inst. Polymerenchem., DAW, Teltow-Seehof, E. Ger.). Faserforsch. Textiltech., 28(10), 497-503 (German) 1977. CODEN: FSTXA7. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 22 The kinetics of radical arylation with benzenesulfonyl chloride (I) [98-09-9] and polyarylation with m-benzenedisulfonyl dichloride (II) [585-47-7] on various arom. compds. showed that thermal anal. of the aryl sulfonyl chloride and substitution of the arom. compds. by aryl radicals proceeded by a first order time-dependence, and that the rate const. of the aryl sulfonyl chloride decompn. at finite concn. was higher than that of the arylation reaction. The relative decompn. rates of 3 aryl sulfonyl chloride followed the sequence II > a-naphthalenesulfonyl chloride [85-46-1] > I.

(European Patent Organization). CODEN: EPXXDW. CLASS: IC: C11D003-39; D06L003-02. APPLICATION: EP 83-305726 26 Sep 1983. PRIORITY: US 82-430562 30 Sep 1982; US 83-532456 16 Sep 1983. DOCUMENT TYPE: Patent CA Section: 46 (Surface Active Agents and Detergents) The bleaching compn. comprise a peroxycarboxylic acid or salt (or diacyl peroxide) and an arom. 937-14-4 which is the cas registry number is also used here. sulfonyl halide as an activator or a peroxygen compd. capable of yielding H2O2 and, as activators, a combination of an arom. sulfonyl halide and a compd. RC(O)L (R = H, alkyl, etc.; L is a leaving group). The compns. provide effective soln. bleaching and/or surface bleaching of textiles over wide classes of stains and soils and wide ranges of soln. temp. and pH. Thus, a bleaching compn. comprising m-chloroperoxybenzoic acid [937-14-4] (to give 3 ppm active O) and 1,3-benzenedisulfonyl chloride [585-47-7] (to give 6 ppm active O available as acyl persulfonate) was added 1 min after the start of the washing cycle in the laundering of tea-, ink-, grass-, and food-stained polyester-cotton fabrics in water (37°) contg. a detergent (contg. anionic and nonionic surfactants) Na5P3O10, zeolite A, and Na2CO3). The compn. gave effective bleaching. .
