The influence of molecular interactions on polymerization—IV

摘要: Abstract The copolymerization of 2-naphthyl methacrylate (2-NM) with methyl (MMA) initiated by 2,2′-azoisobutyronitrile in carbon tetrachloride, chloroform, benzene, acetone and acetonitrile was investigated. reactivity ratios determined the methods Fineman-Ross Kelen-Tudos are: tetrachloride— r 2-NM = 2.46 ± 0.25, MMA 0.61 0.06; chloroform— 2.71 0.30, 0.60 benzene— 2.62 0.44, 0.63 0.11; acetone— 4.13 0.45, 0.06 acetonitrile— 3.70 0.62 0.05. dependence on solvent is explained basis formation complexes between electron-donating naphthalene rings electron-accepting methacrylic double bonds, as indicated NMR studies.
