    Abstract: La présente invention concerne un procédé de synthèse en continu d'un élastomère diénique fonctionnalisé à fort taux de cis, caractérisé en ce qu'il comprend les étapes simultanées: • de polymérisation en continu en milieu très concentré, voire en masse, d'au moins un monomère diénique en présence d'un système catalytique de coordination, jusqu'à atteindre au moins 60% de conversion dans un réacteur de polymérisation dimensionné pour que l'écart type de la fonction de distribution de temps de séjour dans ledit réacteur soit supérieur au temps de séjour moyen divisé par 2Λ/3; • de fonctionnaliser en continu de l'élastomère pseudo-vivant obtenu à l'issue de la polymérisation, par réaction avec un agent de fonctionnalisation dans un malaxeur, par exemple de type autonettoyant. Ce procédé de synthèse, applicable en milieu très concentré, présente une productivité accrue, notamment en permettant d'atteindre un taux de conversion élevé pouvant aller jusqu'à 100% et des taux de fonctionnalisation d'au moins 70%, et permet une flexibilité dans sa conduite.
