Study on the Synthesis and Physical Properties of Polyethylene Imide Derived from HDPE
Polyethylene imide was synthesized from the reaction of high density polyethylene grafted maleic anhydride (PE-g-MA) and 1,4-diaminobutane in boiling xylene. The chemical compositions of the reaction products were examined by Fourier transform infrared spectroscopy. Different conditions and parameters like the effect of temperature, time, monomer concentration and oxygen on the extent of reaction and gel content were studied and the best conditions of the reaction were determined. Thermal analysis using differential scanning calorimetry and thermogravimetry analysis was carried out to determine thermal stabilities and properties of the reaction products. Rheometry experiments were also performed to determine the rheological properties. The results show that PE-g-MA and PE-g-imide have better properties.
