The presence of α-lithio ketone in the initiation mixture formed by a reaction between butyllithium and methyl pivalate was demonstrated. In the initiation of the polymerization of methyl methacrylate α-lithio ketones exhibit high efficiency, which can be enhanced by the effect of lithium alkoxides, in particular of lithium tert-butoxide.
