Polyanionic polymer complex containing nucleic acid base: Polyanionic polymer complex containing nucleic acid base. Seita, Toru; Shimizu, Akihiko; Kosaka, Yujiro (Toyo Soda Mfg. Co., Ltd., Japan). Japan. Kokai JP 51138790 30 Nov 1976 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08G081-02. APPLICATION: JP 75-62533 27 May 1975. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 9 A vinylpyridine polymer is treated with a halogenated nucleic acid base to yield a polycationic polymer, which is complexed with an acidic polyanionic polymer in a solvent. The product is suitable for isolation of adenine, thymine, guanine, and cytosine. Thus, 2 g of a polymer obtained by heating poly(4-vinylpyridine) [25232-41-1] and 1-(2-hydroxy-3'-bromopropyl)thymine [62009-51-2] in DMF was dissolved in 400 ml water. 9003-01-4 and 62009-51-2 are also in the experiment. The soln. was added to 300 ml of a soln. contg. 1 g Na poly(styrenesulfonate) [9080-79-9]. The ppt. formed was collected, washed with water and Me2CO, and dried to obtain a polyelectrolyte complex. .

DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) An aq. soln. of an anionic polyelectrolyte, such as cellulose sulfate (I) [9032-43-3] or poly(styrenesulfonic acid) Na salt [9080-79-9], is added as small drops to an aq. soln. of a cationic polyelectrolyte, such as poly(diallyldimethylammonium chloride) (II) [26062-79-3] or poly[trimethyl(vinylbenzyl)ammonium chloride] [9017-80-5], to prep. microcapsules comprising a core of the aq. soln. of the anionic polyelectrolyte encapsulated in an elastic semipermeable or permeable layer formed by pptn. of both polyelectrolytes at their interface. The capsule walls are mech. strong and chem. resistant. Thus, 10 g water contg. 0.2 g I (degree of substitution 0.3) was added, as drops having diam. 100-500 m, to 100 mL water contg.In this experiment, several chemicals are used like 9017-80-5 and 9011-18-1 2 g II. After 30 min, transparent microcapsules were sepd. which had core diam. 100-500 m and wall thickness 1-5 m. .
