Initiating system comprising at least one initiator and at least one aminoalcoholate of the formula: Image wherein R1, R2 and R4 represent, independently of one another, an alkyl radical, linear or branched, containing 1 to 8 carbon atoms or an aryl alkyl radical, aryl alkyl or aryl radical; R3 and R5 represent, independently of one another, an alkylene radical, linear or branched, containing 2 to 8 carbon atoms, unsubstituted or substituted by an alkyl radical with C1-C8 or aryl or an arylalkylene radical or arylene radical; M designates an alkaline metal and m is equal to 0 or to an integer from 1 to 6, and its application in the preparation of (meth)acrylic (co)polymers (homopolymers, sequenced or statistical copolymers). This initiating system allows for good control of anionic polymerization of these monomers, particularly at low temperatures.

Système d'amorçage comprenant au moins un amorceur et au moins un aminoalcoolate de formule: Image dans laquelle R1, R2 et R4 représentent, chacun, indépendamment, un radical alkyle, linéaire ou ramifié, contenant de 1 à 8 atomes de carbone ou un radical arylalkyle, alkyl aryle ou un radical aryle; R3 et R5 représentent, chacun, indépendamment, un radical alkylène, linéaire ou ramifié, contenant de 2 à 8 atomes de carbone non substitué ou substitué par un radical alkyle en C1-C8 ou aryle ou un radical arylalkylène ou un radical arylène; M désigne un métal alcalin et m est égal à 0 ou à un nombre entier de 1 à 6, et son application à la préparation de (co)polymères (méth)aclyliques (homopolymèrs, copolymères séquencés ou statistiques). Ce système d'amorçage permet un bon contrôle de la polymérisation amionique de ces monomères, en particulier à basse température.
