This invention relates to an initiating system for the anionic polymerization of acrylic monomers, and where necessary vinyl comonomers, including at least one R-M initiator in which M is a metal chosen from among the alkali and alkaline earth metals and R is a linear or branched chain alkyl, aryl, or arylalkyl radical. The polymerization may also take place in the presence of at least one R1OM1 alkali metal alcoholate, in which R is an linear or branched chain alkyl, aryl, or arylalkyl radical and M1 is an alkali metal, on the condition that when M1 is lithium, then R is an aryl or arylalkyl radical. This invention also related to a process for the polymerization of primary, secondary, or tertiary alkyl acrylates, and possibly of vinyl comonomers, in the presence of the initiating system described above.
