Synthesis and characterization of an acrylate polymer containing chlorine-1,3-dioxalane groups in side chains

摘要: Poly[2-(4-chlorophenyl)-1,3-dioxolan-4-yl]methyl acrylate, poly(CPhDMA), was synthesized with radical polymerization process using 2,2′-azobisisobutyronitrile as initiator in 1,4-dioxane at 60°C. The structure of poly(CPhDMA) confirmed by means UV-Vis, FT-IR, 1H-NMR, and 13C-NMR spectral techniques. molecular weight distribution values the polymer were determined gel permeation chromatography (GPC). number-average (Mn), weight-average (Mw) polydispersity index (PDI) to be 10300, 21600 2.097, respectively. thermal degradation kinetics investigated TG/DTG-DTA DSC analyses different heating rates dynamic nitrogen atmosphere. apparent activation energy obtained Flynn-Wall-Ozawa Friedman methods found 91.68 85.23 kJ mol−1, respectively, for decomposition poly(CPhDMA). Also, value calculated Kissinger method based on DTG, DTA data. Then mechanism function it master plots method. Finally, electrical optical properties four-point probe UV-Vis techniques,
