The present invention relates to an initiation system comprising at least one initiator, with the exception of amides of alkaline metals, and at least one alkaline metal alcoholate of the formula ROM, in which M is an alkaline metal and R represents a groupwherein Q is a heterocyclic compound with 5 or 6 chain links, substituted or not, having 1 or 2 oxygen atoms as heteroatoms, R1 and R2 represent an alkylene group, linear or branched at C1-C4, and m is equal to 0, 1, 2 or 3. The present invention also relates to the application of the initiation system to the preparation of (meth)acrylic (co)polymers and, possibly, ethylenically unsaturated monomers that can be copolymerized with (meth)acrylic monomers.
