| Popis: | A study has been made of the kinetics and mechanism of the triethylaluminium initiated polymerization at 0° of methyl isopropenyl ketone (3-methyl-but-3-ene-2-one) in toluene and tetrahydrofuran. The reaction between triethylaluminium and methyl isopropenyl ketone gives rise to a yellow “ate”-complex which rearranges to the initiating species. A rapid production of linear trimer is followed by a slow polymerization giving rise to a bimodal molecular weight distribution. A coordinate mechanism for the polymerization is proposed. |
