Method for the continuous preparation of a catalytic system that is used to polymerize a conjugated diene and installation for implementing same |
摘要 |
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; anda 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). |

1. A process for continuous preparation of a catalytic system that can be used for 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 element(s), said salt being in solution 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, in which R represents an alkyl radical, and H represents a hydrogen atom; and a halogen donor comprising an alkylaluminium halide; which comprises successively in one line: (i) an alkylation reaction between the preforming conjugated diene, with a solution of the salt of rare-earth element(s) and the alkylating agent, the alkylation reaction being carried out for a period of at least 5 minutes in an alkylation reactor composed of at least one well-mixed dynamic mixer; and (ii) addition of said halogen donor to the mixture obtained in (i) that has been removed from the alkylation reactor, and introduction of the mixture obtained in (i) to a continuous halogenation-ageing reactor, to produce a reaction for halogenation-ageing of the preformed catalytic system and to continuously produce said preformed catalytic system at an outlet of said line. |
