| Abstract: | Polymerization of 4-(N, N-dimethylaminobenzyl)methacrylate (DMABMA) initiated by LPO has been studied. The rate equation of the polymerization which was determined at 20, 30, 40 and 50℃ was found to be Rp=Kp DMABMA]1.5 LPO]0.5, and the overall activation energy of this polymerization system was determined as 12.2 Kcal/mol. Owing to the above results and the monomer containing tertiary aromatic amino group, the redox nature of LPO with the monomer itself has been suggested. |
