Free Radical Polymerization of Methyl Methacrylate Using Anthracene Iodine Charge Transfer Complex as Novel Chain Transfer Agent

摘要

Free radical polymerization of methyl methacrylate initiated by α,α'-azobisisobutyronitrile and anthracene iodine charge transfer com- plex as novel chain transfer agent was studied in DMSO at 60 ± 0.1 °C for 2 h under oxygen free condition. The system followed ideal kinetics. The overall activation energy is 43.5 kJ/mol. The average molecular weight is in between 32608-62662. The FTIR spectra shows band at 3020 and 1725 cm~(-1) due to phenyl protons of anthracene charge transfer complex and ester stretching of methyl methacrylate, respectively. The ' H NMR spectra confirms the methoxy protons at 3.7 8 ppm. Thermogravimetric analysis shows the stability of polymer up to 230°C.
