Synthesis and characterization polyvinyl alcohol conjugates with some carboxylic acid and carbonyl compounds

Abstract

Synthesis and characterization of modified PVA polymer have been focused by using advance chemical methods and analytical methods, and its transition metal ions complexes was synthesized. Its characterization is carried out by using, FTIR, XRD, UV-visible spectroscopy and SEM. FTIR shows it is good arrangement with Literature values. UV bands are shifted towards the higher wavelength as the modification in PVA and complexion of modified PVAs, since polymer conjugates show red shift in formal peaks. Also absorbance is increases as modification and complexion. SEM shows solid state study of polymer conjugates also confirmed the semi-compatible nature of the polymer conjugates. XRD of MPVA and CMPVA shows the sharp reflections and diffuse scattering is characteristic of crystalline and amorphous phases of conventional semi-crystalline polymers.
