| titleOfInvention | Method of continuous diene elastomer synthesis |
| abstract | FIELD: chemistry. n SUBSTANCE: method of continuous diene elastomer synthesis is characterized in that it comprises the following simultaneous steps: a) continuous introducing into the polymerization reactor equipped with a gas phase and equipped with, at least, one agitating means and a discharge device, at least: i. one or more monomers to be polymerized, of which, at least, one monomer is a conjugated diene, and ii. from 0 to 70 wt % of the organic solvent based on the total weight of the monomers and solvent, b) continuous polymerizing the monomer or monomers, c) stirring the polymerization medium by continuous moving, at least, one agitator around the axis of rotation, d) continuous discharging the elastomeric mass at the exit from the polymerization step, e) continuous supplying the unloaded elastomeric mass to the cutting device and cutting it into particles of elastomeric mass, f) removing solvent from the elastomeric particle mass and g) removing diene elastomer of the particles produced in the previous step. The method is characterized in that: (1) the degree of conversion is, at least, 60% within the first third of the reaction volume of the polymerization reactor, wherein the volume of the polymerization reactor is understood as the volume present in the reactor between the reactant entry point and the reactor outlet, excluding the discharge device, and (2) the standard deviation of the residence time distribution function in the polymerization reactor is greater than the mean residence time divided by 2√3. An installation for implementing the method and its application have also been announced. n EFFECT: polymerization method is applicable in a medium with a solvent content of up to 70 percent, has increased productivity, which allows achieving high conversion rates without the phenomenon of expansion, is flexible in implementation. n 31 cl, 4 dwg, 3 ex |
