Radical polperization of methyl methacrylate (MMA) initiated with organic peroxide-ditertiaryamine binary systems was studied. Benzoyl peroxide (BPO), lauroyl peroxide (LPO), t-butyl hydro-peroxide (TBH), and t-butyl peroxybenzoate (TBPB) were used as organic peroxide components,aromatic ditertiay amine 4, 4′-tetramethyldiaminodiphenylmethane (TMDAPM) an d aliphatic di-tertiary amine tetramethylethylenediamine (TMEDA) were used as amine components. The polymeri-zation rate R_P, the overall activation energy of polymerization E_a, the rate equation of MMA poly-merization, and the end group of polymer formed were determined.
