METHOD FOR THE CONTINUOUS PREPARATION OF A CATALYTIC SYSTEM THAT IS USED TO POLYMERISE A CONJUGATED DIENE AND INSTALLATION FOR IMPLEMENTING SAME |
摘要 |
<p>The present invention relates to a process for the continuous preparation of a catalytic system that can be used for the polymerization of at least one conjugated diene monomer, said catalytic system being based on at least: a preforming conjugated diene; an organic phosphoric acid salt of one or more rare-earth metal(s), said salt being in suspension in at least one saturated aliphatic or alicyclic and inert hydrocarbon-based solvent; an alkylating agent comprising an alkylaluminium having the formula AlR3 or HAlR2; and a halogen donor comprising an alkylaluminium halide; characterized in that it comprises successively in one line (L): (i) a reaction between the preforming conjugated diene, with the solution of the salt of rare-earth element(s) and the alkylating agent, with the alkylation reaction being carried out for a characteristic minimum period of at least 5 minutes in an alkylation reactor (30) composed of at least one well-mixed dynamic mixer; (ii) the addition of said halogen donor to the mixture obtained in (i), in order to produce a reaction for the halogenation-ageing of the preformed catalytic system and to continuously produce said preformed catalytic system at the outlet of said line (L).</p> |
