Formation of aqueous polymeric two-phase systems: Formation of aqueous polymeric two-phase systems. Zaslavskii, B. Yu.; Levin, V. Yu.; Makhmudov, A. U.; Mestechkina, N. M.; Mikheeva, L. 7681-11-0 and 7778-80-5 are cas registry numbers. These chemicals are also mentioned in this article. M.; Rogozhin, S. V.; Rodnikova, M. N. (Inst. Elementoorg. Soedin., Moscow, USSR). Dokl. Akad. Nauk SSSR, 293(3), 649-53 [Phys. Chem.] (Russian) 1987. CODEN: DANKAS. ISSN: 0002-3264. DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) The compatibility of polymers in a binary aq. system decreases, leading to phase sepn., as the structure of water deteriorates, e.g., on addn. of certain inorg. salts. The effect of salts (KSCN, KClO4, KI, KBr, KCl, KNO3, KF, K2SO4) was studied on Ficoll 400 [26873-85-8]-dextran [9004-54-0]-water. The compatibility of polymers in this system was a function of lyotropic capacity of salt anions. .

Relative hydrophobicity of synthetic macromolecules: Relative hydrophobicity of synthetic macromolecules. II. Poly(vinyl alcohol) with various degrees of acetylation. Zaslavskii, B. Yu.; Mikheeva, L. M.; Rogozhin, S. V.; Davidovich, Yu. A.; Gedrovich, A. V.; Shishkov, A. V.; Gasanov, A. A.; Masimov, A. A. (Inst. Elementoorg. Compd., Moscow 117813, USSR). J. Chromatogr., 291, 203-10 (English) 1984. CODEN: JOCRAM. ISSN: 0021-9673. DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) Partitioning of poly(vinyl alc.) (I) [9002-89-5] of various mol. wts. and degrees of acetylation (from 1% = 18%) in the aq. Ficoll 400 [26873-85-8]-dextran 70 [9004-54-0] 2-phase system was studied at pH 7.4 at varied ionic compns. of the system. The relative hydrophobicity of the polymers was estd. The relative hydrophobicity of I depends on the degree of acetylation of the polymer but not on the mol. wt. in the range from 2 ′ 104 to 1 ′ 105. The results obtained are considered in comparison with those reported previously for polyethylene glycols, polyacrylamides and polyvinylpyrrolidones. The effect of the macromol. nature of a compd. on its hydrophobic character is discussed.
