Peculiarities of radical homo- and copolymerization of acrylic, methacrylic and itaconic acids in complexing solutions

Peculiarities of radical homo- and copolymerization of acrylic, methacrylic and itaconic acids in complexing solutions. Bajoras, G.; Makuska, R. (Dep. Polym. Chem., Vilnius Univ., Vilnius 232600, USSR). Polym. J. (Tokyo), 18(12), 955-65 (English) 1986. CODEN: POLJB8. ISSN: 0032-3896. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 36 Complexation of acrylic [79-10-7], methacrylic [79-41-4] and itaconic acid (I) [97-65-4] in DMSO-water solns. was studied by IR. Quant. assessment was done on the no. of acid mols. entering the H-bonds with DMSO using different amts. of water in the systems. Calcns. were performed on the parameters of electronic structure of I establishing higher acidity of the a-carboxylic group. Reactivity of methacrylic acid in different complexes was assessed according to the redistribution of electron d. in monomer mols. and in acid radicals during complexation. Copolymn. of the acids with acrylonitrile [107-13-1] and methacrylonitrile [126-98-7] in solns. of DMSO-water was investigated as well. Peculiarities and differences of copolymn. of I and monocarboxylic acids in binary solvents was also discussed.

Amphiphilic and polymerizable porphyrins and their copolymerization with phospholipid: oriented fixation of porphyrins in bilayer membrane

Amphiphilic and polymerizable porphyrins and their copolymerization with phospholipid: oriented fixation of porphyrins in bilayer membrane. Nishide, Hiroyuki; Yuasa, Makoto; Hashimoto, Yukio; Tsuchida, Eishun (Dep. Polym. Chem., Waseda Univ., Tokyo 160, Japan). Macromolecules, 20(2), 459-61 (English) 1987. CODEN: MAMOBX. ISSN: 0024-9297. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 6, 36, 38 Novel, amphiphilic and polymerizable porphyrin derivs. (A) were synthesized by reaction of hydroxy-contg. porphyrin derivs. with muconic chloride [20578-72-7] or itaconic acid [97-65-4], followed by metal insertion. The A had a high compatibility with lipids and formed a stable bilayer membrane with a polymerizable phospholipid. The A were copolymd. with the phospholipid in a bilayer state and were covalently and oriented in a bilayer membrane.
