The invention relates to a process for the preparation of a polymeric mixture, comprising a first polymerization step in which substantially monomer M is reacted by atom transfer radical polymerization in a mixture which contains a transition metal salt, a ligand having at least two chelating sites, an atom transfer radical polymerization initiator, a reducing agent and monomer M, and a second polymerization step in which monomer S substituted by silyl groups is added to the mixture obtained from the first polymerization step, so that monomer S substituted by silyl groups is reacted by atom transfer radical polymerization in the mixture obtained from the first polymerization step. The polymeric mixture obtained is used as a binder additive for sealants.

L'invention concerne un procédé pour la production d'un mélange polymère. Le procédé selon l'invention comprend une première étape de polymérisation dans laquelle on fait pratiquement réagir un monomère M par polymérisation radicalaire par transfert d'atomes dans un mélange qui contient un sel de métal de transition, un ligand au moins bidendate, un amorceur de polymérisation par transfert d'atomes, un agent réducteur et le monomère M, ainsi qu'une deuxième étape de polymérisation dans laquelle on ajoute au mélange obtenu lors de la première étape de polymérisation un monomère S à substitution silyle de manière à faire réagir le monomère S à substitution silyle par polymérisation radicalaire par transferts d'atome dans le mélange obtenu lors de la première étape de polymérisation. On utilise le mélange polymère obtenu comme additif liant pour des agents d'étanchéité.
