The influence of molecular interaction on polymerization: The influence of molecular interaction on polymerization. 8. Copolymerization of monomethyl itaconate with 2-naphthyl methacrylate. Boudevska, H.; Todorova, O. (Cent. Lab. Polym., Sofia 1000, Bulg.). Makromol. Chem., 185(2), 353-62 (English) 1984. CODEN: MACEAK. ISSN: 0025-116X. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) The copolymn. was investigated of monomethyl itaconate (I) [26248-95-3] with 2-naphthyl methacrylate (II) [10475-46-4] initiated with AIBN in solvents of different dielec. consts. and capability to form H bonds. The reactivity ratios (r) of the monomer pairs in the different solvents are as follows (solvent, r for I, and r for II given, resp.): CHCl3, 2.44 ± 0.19, 1.20 ± 0.28; 1,4-dioxane, 0.49 ± 0.Several substances with their cas registry numbers 89737-94-0 and 26248-95-3 may be metioned in this study.04, 0.97 ± 0.29; acetone, 0.15 ± 0.00, 0.28 ± 0.03; MeCN, 0.10 ± 0.01, 0.35 ± 0.14. IR and 1H NMR spectroscopy studies showed the influence of the solvent on the capability of the monomers to form H bonds and donor-acceptor assocs. The changes in the reactivity ratios of both monomers were attributed to the interaction obsd. between the monomer mols. as well as between the mols. of the monomers and the resp. solvent. .

Luminescence studies in vinyl polymers containing aromatic groups: Luminescence studies in vinyl polymers containing aromatic groups. Abuin, Elsa B. (Fac. Quim., Pontif. Univ. Catol. Chile, Chile). Contrib. Cient. Tecnol., 13(Numero Espec.), 57-60 (English) 1983. CODEN: CCTEDC. ISSN: 0716-0127. DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) The quantum yield of excimer emission in Me methacrylate-4-vinylbiphenyl copolymer [82530-42-5] increases and the monomeric emission decreases as the fraction of 4-vinylbiphenyl (I) units decreases. Excimer formation in the copolymer strongly depends on the possibility of energy migration along sequences of I units. The rate const. of intermol. excimer formation is larger for Me methacrylate-2-naphthyl methacrylate copolymer [73970-14-6] than for 2-naphthyl methacrylate [10475-46-4], and the rate const. increases as the naphthyl group content of the polymer increases.
