摘要： A polymer synthesis system has a polymerization reactor and a deliquifying-quench extruder downstream of and in fluid communication with the polymerization reactor. The polymerization reactor has an inlet and an outlet with a rotatable shaft positioned axially within the reactor. The deliquifying-quench extruder has an inlet and an outlet, with a shaft assembly positioned axially within the extruder. The shaft assembly includes multiple helical flight configurations and multiple processing zones defined by the multiple flight configurations. The processing zones include an extraction-compaction zone, a sealing zone downstream of the extraction-compaction zone, a vent-cooling zone downstream of the sealing zone, a quenching zone downstream of the vent-cooling zone, and a conveying zone downstream of the quenching zone.

摘要： Polymerization process, in particular for the polymerization of monomer selected from ethylene and propylene in a reaction system containing at least three reactors operated in series. The process includes (a) polymerizing monomer in a first reactor having a volume of at least 50 m3 to produce a first polymer, (b) passing the first polymer to a second reactor and polymerizing monomer in the second reactor to produce a second polymer containing the first polymer and polymer produced in the second reactor, and (c) passing the second polymer to a third reactor and polymerizing monomer in the third reactor to produce a third polymer containing the second polymer and polymer produced in the third reactor. The polymerizations are performed such that between 0.01 and 5 w % of the total mass of the third polymer is polymer produced in the second reactor.

摘要： Process for enhancing the separation of monomer components from light components other than monomer by providing a first stream containing monomer and light components other than monomer and passing the first stream to a first separator at a first pressure to separate a gaseous second stream containing at least some of the light components other than monomer and provide a liquid third stream containing monomer. A portion of the third stream and a fourth stream containing monomer and light components other than monomer is passed to a second separator at a second pressure which is lower than the first pressure to separate a gaseous fifth stream containing at least some of the light components other than monomer from the fourth stream and provide a liquid sixth stream containing monomer.

摘要： Methods and systems for pelletizing low molecular weight semi-crystalline polymers are provided herein. Polymer compositions comprising the semi-crystalline polymer and a solvent are provided to a devolatilizing device, where the solvent is at least partially evaporated under vacuum conditions, resulting in removal of heat from the polymer by evaporative cooling and crystallization of the polymer. Once the polymer has reached the desired temperature, the polymer exits the devolatilizer and is pelletized. Semi-crystalline polymers that may be used in the present invention include propylene-based copolymers, such as propylene-ethylene and propylene-hexene copolymers having a heat of fusion, Hf, from about 5 to about 75 J/g and a weight average molecular weight, Mw, from about 10,000 to about 200,000 g/mol.
