The synthesis and characterization of modified polyvinyl alcohol conjugates was studied by using modified chemical method. Characterizations of MPVA were carried out by using FTIR, 1HNMR, XRD. It showed that, for MPVAs, compatibility between the amorphous components of both homopolymers is possible. Thus, it can be suggested that the crystal forms in PVA do not prevent the compatibility between amorphous regions of the two polymers. Fourier transform infrared FTIR spectra of all polymer conjugates under investigation were recorded between 400 and 4000cm-1. 1H NMR gives the information about the various types of protons present in the polymer conjugates.
