Copper
Catalyst Removal Technology
Atom
Transfer Radical Polymerisation has several advantages
in the industrial production of polymers:
The
polymerisation reaction is usually mediated by a Cu(I)
catalyst bound to a standard bidentate amine ligand.
Unfortunately,
ATRP leaves a high residue of Cu species from the catalyst
as contaminants in the end product. Existing filtration,
ion exchange and other chemical methods of removing
the catalyst residue are uneconomic or unwieldy.
Meridian
has designed a magnetophoretic - dielectrophoretic filter
that can extract the contaminating copper species in
either a batch or a continuous production process environment.
Auxiliary photophoresis may also be incorporated for
greater efficiency. This filter promises extraction
of very high levels of catalyst contaminant extremely
cheaply, without the need for expensive ion exchange
media or filters that will become clogged by the polymer.
Continuous production is assured.
