One-pot and One-step Cu(0)-mediated Reversible-Deactivation Radical Polymerization of N-Isopropylacrylamide (NIPAM) in Water
The well-controlled NIPAM polymerization was realized in water with narrow MWDs and varied MWs via a facile one-pot and one-step Cu(0)-mediated RDRP. Sufficient CuI at the very beginning is the key for kicking off the Cu(0)-mediated NIPAM RDRPs
and adequate deactivation strength during the polymerization process is the key to achieve a well-controlled chain growth.
Abstract
Copper(0)-mediated reversible-deactivation radical polymerization (Cu(0)-mediated RDRP) of the water-soluble monomer
N
-isopropylacrylamide (NIPAM) has been challenging with the problems of high dispersity
poor control over the molecular weights (MWs) or complex or multi reaction steps
etc
. In this work
we report the well-controlled polymerization of NIPAM in water
via
a facile one-pot and one-step Cu(0)-mediated RDRP. The results of this approach show that the key for kicking off the Cu(0)-mediated NIPAM RDRPs is to ensure sufficient Cu
I
at the very beginning
and the key to achieve a well-controlled chain growth is to provide adequate deactivation strength during the polymerization process. For NIPAM
which has a high propagation rate constant
the deactivation control can be effectively enhanced by extra adding deactivator (
i.e.
Cu
II
) to the system. Moreover
a low reaction temperature (4 °C) is necessary in the controlled synthesis of higher MW poly(
N
-isopropylacrylamide) (PNIPAM) to avoid the compromise in control caused by the phase transition from its lower critical solution temperature (LCST). Through this new kinetically controlled strategy
PNIPAMs with well-defined structure
narrow molecular weight distributions (MWDs) and varied MWs were successfully achieved.
