CONTINUOUS SYNTHESIS METHOD FOR A MODIFIED DIENE ELASTOMER, FACILITY FOR IMPLEMENTING SAME

摘要

The present invention relates to a continuous synthesis method for a diene elastomer incorporating a step for modifying the diene elastomer in a functionalisation device, said step being characterised by: - a kinetic model according to which the ratio of the kinetic constants is greater than 1, and - a flow reflected by a residence time distribution in the functionalisation device expressed according to equations 1 or 3: (i) in a functionalisation device with at least one tubular continuous reactor or with at least one cascade of at least two stirred reactors (Eq. 1), (ii) in a functionalisation device that is a combination of device (i) and a device with at least one continuous stirred reactor, having a residence time distribution characterised by the following equation (Eq. 2), the device (ii) having a residence time distribution characterised by the following equation 3, which is the result of the convolution of equations 1 and 2 (Eq. 3).
