Abstract: In some embodiments a process includes introducing an aqueous solution to a first hydrocarbon solvent to form an emulsion, wherein the aqueous solution comprises an oxidizing agent containing solution and a surfactant containing solution. The process further includes introducing a cement to the emulsion to form a first mixture within a reactor, wherein the cement comprises a butyl rubber elastomer and a second hydrocarbon solvent that is the same as or different than the first hydrocarbon solvent. The process further includes introducing a halogen source to the first mixture contained within the reactor to form a second mixture comprising a halobutyl rubber elastomer. The process further includes introducing a neutralizing agent with the second mixture to form a third mixture. The process further includes isolating the halobutyl rubber elastomer from the third mixture.

Abstract: 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.
