Detection and determination of 5-sulfoisophthalic acid in copolyamides: Detection and determination of 5-sulfoisophthalic acid in copolyamides. Mueller, H.; Rossbach, V.; Zahn, H. (Dtsch. Wollforschungsinst., Tech. Hochsch. Aachen, Aachen, Ger.). Angew. Makromol. Chem., 56(1), 151-6 (English) 1976. CODEN: ANMCBO. DOCUMENT TYPE: Journal CA Section: 39 (Textiles) Section cross-reference(s): 80 5-Sulfoisophthalic acid [22326-31-4] is sepd. from hydrolyzed .epsilon.-caprolactam copolyamides by ion-exchange chromatog. and identified in the eluate by thin-layer chromatog., high-voltage electrophoresis, or thin-layer electrophoresis. After detn. of the comonomers the amt. of Na 3,5-dicarboxybenzenesulfonate [6362-79-4] is detd. directly in the polymer by x-ray fluorometric S anal. and flame-photometric Na anal. Application of these techniques to 2 anionically-modified com. polyamide 6 fibers of the differential dyeing type is discussed.

Coesterification of terephthalic acid and sodium sulfoisophthalate with ethylene glycol during synthesis of the copolyester: Coesterification of terephthalic acid and sodium sulfoisophthalate with ethylene glycol during synthesis of the copolyester. Baranova, T. L.; Repina, L. P.; Aizenshtein, E. M. (USSR). Khim. Volokna, (3), 30-1 (Russian) 1978. CODEN: KVLKA4. ISSN: 0023-1118. DOCUMENT TYPE: Journal CA Section: 39 (Textiles) Na sulfoisophthalate (I) [6362-79-4] has no effect on the polymn. kinetics of terephthalic acid (II) [100-21-0] with ethylene glycol (III) [107-21-1] but increases the no. of undesired side reactions which can be ignored at ￡3% I and <533K. The copolymn. of 1:1.5 II-III with 1-5% I was examd. at 513-53K and 600-14,000 s. The copolymn. was a 1.5-order reaction with respect to COOH groups, and the activation energy was 95.3 kJ/mol which agreed well with published data for II esterification with III.
