Definitions

  • Isobutylene-based polymer refers to polymers comprising at least 80 mol % repeat units from isobutylene.
  • Quench or “quenching” refers to the process of rapidly heating and mixing the slurry from the reactor with a quench medium, usually water and/or steam, wherein further polymerization is terminated.
  • a quench medium usually water and/or steam
  • the slurry can leave the reactor colder than -90°C and enter the flash tank at 60° C.
  • the polymer may be produced in continuous or batch processes.
  • the reactor may be a plug flow reactor, a continuous stirred tank reactor, a boiling pool reactor, and/or other reactors which facilitate flow and interaction of the monomers and catalyst.
  • reactors useful for producing isobutylene based or butyl polymers at temperatures less than 0°C are referenced as "butyl reactors.”
  • Illustrative examples include any reactor selected from the group consisting of a continuous flow stirred tank reactor, a plug flow reactor, a moving belt or drum reactor, a jet or nozzle reactor, a tubular reactor, and an autorefrigerated boiling-pool reactor.
  • primary C 4 to Cs alcohols are selected as providing the desired characteristics for a quench agent.

Abstract

L'invention concerne un système et un procédé pour polymériser un polymère, selon lesquels l'effluent du réacteur est désactivé avec un alcool à chaîne linéaire ou ramifiée possédant quatre à douze atomes de carbone pour former un complexe soluble avec le catalyseur résiduel dans l'effluent.
