Synthesis, Characterization and Testing of Emulsion Polymerized Vinyl Acetate –Acrylamide Copolymers for Bio-Degradable Applications

Abstract

Vinyl Acetate was copolymerized with Acrylamide in Four different formulations (95:05%, 90:10%, 85:15% and 80:20 %) (wt%) using redox-catalysts by emulsion polymerization at 45 Deg C in water. The emulsions were casted on glass plates to form films. The films were tested for Mechanical properties like tensile strength, elongation at break and tear strength. Water vapour Permeability was determined. Optical property Haze was determined. The films were characterized by FT –IR spectroscopy and by DSC(Differential Scanning Calorimetry) for Tg, Tm and Td. The emulsions were precipitated using non solvent Methanol. The copolymers films were used for testing of MFI to know the flow characteristics.
