- Abstract:
- A novel tetradentate amine ligand namely N,N,N',N'',N''',N'''-hexaoligo(ethylene glycol)
triethylenetetramine (HOEGTETA) was employed in the homogenous ATRP of MMA in anisole
using CuBr and CuBr2 as the catalyst and ethyl 2-bromoisobutyrate (EBiB) as an initiator. The
effect of the polymerization temperature and
the various ratios of Cu(I) to Cu(II) were investigated
in detail. Moreover, we demonstrated
the ATRP of MMA by using only Cu(II) in the
absence of any free radical initiator, reducing
agent, or air. The ATRP of MMA with the use
of only Cu(II) and HOEGTETA or N,N,N',N'',
N''-pentamethyldiethylenetriamine (PMDETA)
resulted in well-defined PMMA.
