Definitions

  • the invention relates to a process for carrying out polymerization processes, wherein in a first stage a (co) polymerization of monomer (s) and in a second stage, a separation of product and monomers, oligomers, reaction products and additives or solvents takes place.
  • PLA polylactide

  • the task is to use a preferably two-stage process of the o.g. To develop type in which the polymerization and in particular a devolatilization or Finishen are optimally performed overall.
  • a substance is added to the reaction mixture, by means of which a stripping and / or a temperature influence takes place, whereby the reaction equilibrium is shifted towards the polymers, whereby the reaction rate to the monomer is slowed down.
  • a substance is added to the reaction mixture, by which a stopping and, as a second function, a stripping and / or a temperature influencing takes place.
  • the polymerization of the PLA is an equilibrium reaction which can be brought to fantastic conversions of from 90% to 100%, typically 91% -95%, for example 93%, using the inventive technology (existing technologies stop at 50 to 80% conversion).

But other higher alcohols C & to Cio, such as octanol, may be suitable.

Abstract

L'invention concerne un procédé pour la mise en œuvre de processus de polymérisation. Lors d'une première étape a lieu une (co-) polymérisation d'un ou de plusieurs monomères et lors d'une seconde étape a lieu une séparation du produit et des monomères, des oligomères, des produits de réaction ainsi que des additifs ou des solvants. Avant et/ou lors de la seconde étape, c'est-à-dire à la fin, une substance doit être ajoutée au mélange réactionnel, grâce à laquelle un entraînement et/ou une influence de la température se produit, ce qui permet de déplacer l'équilibre réactionnel vers les polymères, la vitesse de réaction vers le monomère étant ralentie. Une seconde possibilité prévoit que, avant et/ou lors de la seconde étape, c'est-à-dire à la fin, une substance est ajoutée au mélange réactionnel, grâce à laquelle un arrêt et en tant que seconde fonction un entraînement et/ou une influence de la température se produisent.
