Online published on 26 March, 2018. Abstract A thin film of guar gum modified with polyvinyl alcohol (PVA) was prepared with tamarind seed kernel powder (TKP) by condensation polymerization method. In this method a redox pair of ascorbic acid and potassium persulphate was used. This initiate the reaction and poly vinyl alcohol grafted over guar gum. TKP was added by changing temperature and a thin film was prepared. Characteristics of newly synthesized film was determined by Fouriour transform Infrared spectrum(FT-IR), Thermogravimetric analysis(TGA), Nuclear Magnetic Resonance(NMR), Mass spectra, Scanning Electron Microscopy(SEM), elemental analysis etc. Top Keywords condensation polymerization, PVA modified guar, redox pair, NMR, SEM, MASS spectra etc. Top |
