摘要：
Free radical polymerization of methyl methacrylate initiated by alpha,alpha'-azobisisobutyronitrile and anthracene iodine charge transfer complex as novel chain transfer agent was studied in DMSO at 60 +/- 0.1 degrees 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 FUR 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-1 NMR spectra confirms the methoxy protons at 3.7 delta ppm. Thermogravimetric analysis shows the stability of polymer upto 230 degrees C.
