Résumé en anglais
The reaction between benzophenone and TMA was investigated in details at 20 degrees C for different TMA/benzophenone (r) ratios. For r = 2, a heterodimer mu-(1,1-diphenylethoxy)-mu-methyl-tetramethyldialuminium (B) is only ...Lire la suite >
The reaction between benzophenone and TMA was investigated in details at 20 degrees C for different TMA/benzophenone (r) ratios. For r = 2, a heterodimer mu-(1,1-diphenylethoxy)-mu-methyl-tetramethyldialuminium (B) is only formed. The latter was found able to activate MeDIP(2,6-iPrPh)(2)FeCl2 catalyst towards ethylene polymerization. Such catalytic system leads to the formation of high molar mass polyethylene with a broad molar mass distribution, without the presence of oligomers, that is attributed to a strong reduction of the transfer reaction to TMA< Réduire
