Abstract
`The kinetics of the polymerization of methyl methacrylate initiated b y lithium alkyls (tert-butyllithium or ethyl alpha-lithiobutyrate) was investigated in the presence of aluminium alkyls (triethylaluminium o r triisobutylaluminium) in toluene at -78 degrees C. The rate of polym erization decreases considerably once the living dimer is formed. This suggests that the aluminate end-group coordinates with the penultimat e ester group of the polymer chain, thus decreasing reactivity. The re sults are at variance with an activated monomer mechanism.
