Preparation of a polymeric membrane with lipoamide structure and its application to electron transport across membrane. Nambu, Yoko; Endo, Takeshi; Okawara, Makoto (Res. Lab. Resourc. Util., Tokyo Inst. Technol., Yokohama 227, Japan). J. Polym. Sci., Polym. Chem. Ed., 23(1), 223-30 (English) 1985. CODEN: JPLCAT. ISSN: 0449-296X. DOCUMENT TYPE: Journal CA Section: 38 (Plastics Fabrication and Uses) A lipoamide (LAm) structure was introduced into a polymeric membrane by chem. modification of poly(g-methyl-D-glutamate [25767-60-6]. A redox reaction proceeded across the membrane between methylene blue [61-73-4] and tetramethylammonium borohydride [16883-45-7] or Bu3P [998-40-3] mediated by pendant LAm groups as solid carriers. It is suggested that the electron transport process in the membrane is derived from the exchange reaction between reduced LAm (thiol) and LAm (disulfide).

CODEN: JKXXAF. CLASS: IC: C08G061-08. APPLICATION: JP 75-109587 10 Sep 1975. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) Diethylaluminum chloride [96-10-6], WCl6, and Ph3P [603-35-0] or Bu3P [998-40-3] were used as catalysts to prep. poly(5-methoxycarbonyl-bicyclo[2.2.1]heptene-2) (I) [27176-60-9] in good yields. Thus, 100 parts 5-methoxycarbonyl-bicyclo[2.2.1]heptene-2 was mixed with 2 parts WCl6, stirred for 10-20 min, mixed with 2.6 parts Ph3P, 400 parts (vol.) toluene, and 20 parts (vol.) hexane contg. 1.5 parts Et2AlCl, and polymd. at 15-25.degree. for 20-4 h to prep. 92% I.
