A novel polymer blend based on sodium humate/PVP/PEG

Abstract

The formation of complexes between polyvinylpyrrolidone (PVP) and sodium humate (SH) with polyethylene glycol (PEG) 300 was prepared by strong intermolecular interaction involving the formation of hydrogen bonds between the carbonyl group of PVP and hydroxyl groups and -NH2 of SH. The stability of the complex passed through an extreme value as a function of 15% SH and 10% PVP with 1% of PEG300 in an aqueous solution. The samples were further characterized by means of FTIR and SEM. The effects of polymerization variables including different reaction temperatures in various pH, content of SH, the weight ratio of PVP to PEG300 in distilled water were studied. The result from FTIR spectra showed that PVP and SH participated in graft polymerization reaction with PEG and hydrogen-bonding interaction occurred between PVP and SH. The optimum complex formation was obtained in pH 12 at 100°C. The result polymer blend was considered as a dermacosmetic drug in human and animal skin diseases, as an adhesive agent in board production, as a stabilizer agent in dye formulations, and as a film protector in wood surfaces.
