Process and apparatus for continuously polymerizing cationically polymerizable monomers

摘要

The present invention relates to a process and to an apparatus for continuous living polymerization of cationically polymerizable monomers, in which at least three feedstocks are mixed in one or more mixers with microstructures and then polymerized in at least one reaction zone.

1. A process for continuously polymerizing cationically polymerizable monomers, the process comprising:
(a) mixing at least two liquid streams, to obtain a reaction mixture comprising at least one cationically polymerizable monomer,
wherein the at least two liquid streams each independently comprise one or more of the following components:
at least one cationically polymerizable monomer;at least one initiator;at least one catalyst; andat least one electron donor,with the proviso that at least one of the at least two liquid streams comprises the cationically polymerizable monomer,wherein a stream comprising the at least one catalyst does not comprise any initiator or any electron donor,wherein when the at least two liquid streams comprise more than two liquid streams the streams can be mixed successively or simultaneously, andwherein at least one mixing operation occurs in a mixer having microstructures with a characteristic dimension from 10 to 1000 μm; and (b) polymerizing the reaction mixture in at least one reaction zone.
