摘要： The invention relates to a method for preparing decontaminated natural rubber. The method is characterised in that it includes a decontamination step in which wet natural rubber coagulum is passed through a system comprising an extruder and a filter installed at the extruder outlet, said extruder having an axially symmetrical grooved sheath provided with grooves in its thickness that open at the inner surface of the sheath. The method is also characterised in that the sheath is such that, in any plane perpendicular to the axis of the sheath, with R (expressed in mm) being the distance between the centre of the sheath and the inner surface of the sheath: a. the ratio (total length of the groove openings, expressed in mm)/(2πR), denoted A, is at least equal to 0.25 and at most equal to 0.9; b. the ratio (number of grooves/2R), denoted B, is greater than or equal to 0.1; c. the ratio (depth of grooves expressed in mm)/(2R), denoted C, is greater than 0.02; and d. the plane that passes through the two bottom edges forms, together with each plane passing through a bottom edge and an intersection edge, defining a side face, an angle δ at least equal to 60° and at most equal to 90°.

摘要： 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.
