FIELD: chemistry.
SUBSTANCE: invention relates to the functionalized diene elastomer continuous synthesis method. Diene elastomer continuous synthesis method comprises the following simultaneous stages: related to the polymerization stage comprises: a) continuously introducing into the having the gas phase and equipped with at least one stirring rotor and discharge device polymerization reactor, of at least: i. one coordination catalysis system, ii. at least one conjugated diene monomer for polymerization, and iii. from 0 to 70 wt% of organic solvent based on the monomer (s) and solvent total weight; b) monomer (s) continuous polymerization using the means necessary to achieve the conversion degree of at least 60% within the first third of the polymerization reactor reaction volume; c) mixing the polymerization mixture by at least one stirring rotor continuous movement about the axis of rotation; d) pseudo-living elastomer paste continuous unloading obtained as a result of the polymerization; where the residence time distribution function in the polymerization reactor standard deviation is greater than the result of the average residence time division by 2√3, relating to the functionalization stage includes: e) this paste continuous transfer to the having gas phase kneader, stirring device comprising at least one stirring rotor and discharging device; f) functionalizing agent continuous introduction into the kneading machine, corresponding to the AR1-B formula, where A is the group capable of reacting with the pseudo-living elastomer reactive end, R1 designates atom or group of atoms forming bond between A and B, and B is functional group capable of interacting with the reinforcing filler; g) pseudo-living elastomer continuous functionalization by interaction with the functionalizing agent in the said kneading machine; h) obtained at the preceding stage functionalized elastomer paste continuous discharging; i) functionalized diene elastomer isolation.
EFFECT: technical result is that this synthesis method is applicable to the highly concentrated mixture, characterized by the increased productivity, in particular by providing a high degree of conversion, which can reach 100% and functionalization degrees of at least 70%, and provides flexibility of the process implementation.
