摘要

B PREPARATION PROCESS CONTINUED FROM A CATALYTIC SYSTEM USED FOR POLYMERIZATION AT LEAST ONE MONEMUM OF CONJUGATED DIENE, INSTALLATION FOR THE APPLICATION OF THE SAME AND CONTINUOUS PREPARATION PROCESS AT LEAST ONE PICTURE BY A PRESENT A LEVER refers to a process of continuously preparing a catalytic system usable for the polymerization of at least one conjugated diene monomer, said catalytic system being based on at least: - a preformed conjugated diene, - a salt of a or several rare earth metals (s) of an organic phosphoric acid, said salt suspended in at least one aliphatic or alicyclic inert and saturated hydrocarbon solvent, - an alkylating agent comprising an alkylaluminum of formula AlR3 or HA1R2, and - a halogen donor comprising an alkylaluminum halide, characterized in that it successively comprises in one and the same line (L): (i) a reaction between the preforming conjugated diene and the rare earth salt (s) solution and the alkylating agent, and the conduct of the alkylation reaction for a minimum characteristic duration of at least 5 minutes in an alkylation reactor (30) comprising at least one perfectly stirred type dynamic mixer, (ii) an addition to the mixture obtained in (i) of said halogen donor for conducting a reaction of halogenation-aging of the preformed catalytic system and continuously obtaining said preformed catalytic system at the outlet of said line (L).
