Abstract

L'invention porte sur un procédé de production de cis-1,4-polybutadiène ayant une faible teneur en gel. Ce procédé consiste à polymériser 1,3 butadiène en présence d'un catalyseur et d'un diluant de polymérisation. Le diluant de polymérisation comprend un solvant organique et des particules d'eau dont la taille moyenne est inférieure ou égale à environ 10µm. En régulant la taille moyenne des particules de l'eau présente dans le diluant, la teneur en gel du produit polymère peut être réduite.
