Definitions

  • olefin polymers are chlorinated or chlorosulfonated in solution or suspension in monofluorobenzene and are isolated substantially in the absence of oxygen by means of a series of extruders to produce chlorinated or chlorosulfonated products having low levels of residual solvent and solvent by-products, in particular less than 0.5 weight percent.
  • olefin polymers is meant homopolymers and copolymers of C2-C8 alpha-monoolefins, including graft copolymers.
  • the copolyme r s may be dipolymers or higher order copolymers, such as terpolymers or tetrapolymers.

Abstract

Procédé de préparation de polymères oléfiniques chlorés et chlorosulfonés contenant de faibles taux de solvant résiduel selon lequel on utilise comme milieu de réaction du monofluorobenzène et on isole le polymère à l'aide d'une série d'extrudeuses ventilées à boucle fermée. Ce procédé permet également de supprimer la formation d'un sous-produit tel que le monochloromonofluorobenzène.
