| titleOfInvention | Process for continuous synthesis of a diene elastomer |
| abstract | The present invention relates to a process for continuous synthesis, in a highly concentrated medium, of diene elastomers with a high degree of conversion, which comprises the following simultaneous steps: a) continuously introducing, into a polymerization reactor which has a gas phase and is equipped with at least one stirrer rotor and with a discharge device, at least i. one or more monomers to be polymerized, including at least one conjugated diene monomer, and ii. from 0% to 70% by weight of an organic solvent, calculated relative to the total weight of monomers + solvent, b) continuously polymerizing the monomer(s), c) stirring the polymerization medium by continuous movement of at least one stirrer rotor about a rotary shaft, d) continuously discharging the elastomer paste resulting from the polymerization, e) continuously conveying the discharged elastomer paste to a cutting device and cutting said paste into particles, and f) removing the solvent from the particles of the elastomer paste and g) recovering the diene elastomer from the particles obtained, and is characterized in that 1‑ the degree of conversion is at least 60%, at the limit of the first third of the reaction volume of the polymerization reactor, and 2‑ the standard deviation of the distribution function for residence time in the polymerization reactor is greater than the mean residence time divided by 2√3. This polymerization process, which is applicable in a highly concentrated medium, exhibits increased productivity, in particular making it possible to achieve a high degree of conversion which can be up to 100%, and allows flexibility in terms of the implementation thereof. |
