Polymer characterization
The chemical structure was characterized with a Perkin
Elmer Fourier Transform Infrared microscopy using opti-
cal Perkin Elmer software. The line-scan spectra were
based on 32 scans and a resolution of 4 cm1
.
1
H NMR
spectra were recorded at 25°C on a Bruker AM300 spec-
trometer. The polymer samples were dissolved in chloro-
form and a drop of TMS (tetra methyl silane used as
internal standard for calibrating chemical shift for
1
H)
was added as reference. 10 mg of the sample dissolved in
1 ml of deutered solvent was used
