FTIR spectra of all polymer
conjugated under investigation were recorded on Shimadzu
FTIR-8101A Spectrophotometer between 400 and 4000 cm.
-1.XRD patterns of the modified PVA samples were recorded at
using Phillips PW-1700, automatic X ray-diffractometer using
Cu Kα radiation of wavelength 1.544 A0
. UV-Visible spectra
of MPVA were recorded on Shimadzu UV-1800
Spectrophotometer, thin films by placing an uncoated identical
Conducting glass substrate in the reference beam in the range
of 200 to 800 nm. A plot of absorption coefficient verses
wavelength for all synthesized samples and Wavelength for
maximum absorbance λmax and corresponding optical band
gap for all samples. The 1H NMR spectra of polymer
conjugates were taken in a DMSO using TMS as internal
standard on Brucker Auance-II 400 NMR spectrometer on 300MHz
and 75 MHz respectively. The chemical shifts measured are in PPM.
