| Abstract: | Three kinds of effects like triphenylamine nucleophiles in carbocationic polymerization were further confirmed by studying carbocationic polymerization of diphenylamine,N-methyl aniline, N,N-dimethyl aniline and their derivatives in Dicumyl/TiCl 4/IB and TiCl 4/IB and UV spectra. The mechanism of carbocationic polymerization of diphenylamine, N-methyl aniline, N,N-dimethyl aniline was obtained by combining the activation energy of neucleophiles in trapping proton, obtained by computer simulation, and result of analyzing the molecular weight distribute GPC,polymer molecular weight, obtained from polymerization of aniline derivativesin Dicumy1/TiCl 4/IB. |
