These chemicals are also mentioned in this article. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08G063-30. APPLICATION: JP 82-41566 16 Mar 1982. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Transparent polymers are readily prepd. by condensing a poly(ethylene terephthalate) prepolymer with 0.1-30 mol% oxyethylated bisphenol A in the presence of a sulfonic or sulfinic acid catalysts. Thus, 1 part 1:1.5 terephthalic acid-ethylene glycol prepolymer was polymd. with 0.05 mol bisphenol A bis(hydroxyethyl) ether using 0.1 mmol (on terephthalate) p-ClC6H4SO3H [98-66-8] at 285°/0.1 mm for 2 h to give a transparent copolymer [25640-01-1]. .

Synergistic inhibition of the acid corrosion of steel: Synergistic inhibition of the acid corrosion of steel. Ledovskikh, V. M. (Kiev. Politekh. Inst., Kiev, USSR). Zashch. Met., 20(1), 54-61 (Russian) 1984. CODEN: ZAMEA9. ISSN: 0044-1856. DOCUMENT TYPE: Journal CA Section: 55 (Ferrous Metals and Alloys) Synergistic corrosion inhibitors are based on cationic quaternary pyridinium salts with anionic addns. of compds. contg. org. (esp.-CO2OH) or inorg. (-SO3H, HS, -NHCSNH-, or halides) groups. Protection of steel from acid corrosion was related to inhibitor mol. structure. An example is given for the protection of steel 08kp [11103-16-5] in 3M H2SO4 with inhibitor mixts. based on KPI-3 [39301-67-2]. Anionic carboxyl, sulfoxide, thiourea, sulfide, and halogenide groups were effective for the synergistic inhibition of corrosion.Except for chemicals metioned above, 98-66-8 and 89444-70-2 are also used. .
