Abstract

Polymers have been synthesized from renewable resource based from waste cooking oil using 4,4-diphenylmethane diisocyanate (MDI) as cross linking agents. Waste cooking oil was obtained from Small Medium Industries (IKS's) and was chemically manipulated at the laboratory scale. The preparation of the bio-monomer was divided into two stages, beginning with the preparation of catalyst and second stage is the acid-catalysed ring- opening of epoxies to form polyols. The properties of these materials were examined by the Fourier Transform Infrared spectroscopy (FTIR), Tensile Test (BS 527-1 :1993) and Scanning Electron Microscope (SEM), and the results were compared with virgin oil polymer. FTIR test shows that the characteristic of ester bands for virgin oil polymer and waste cooking oil polymer at 1743 cm -'and 1744 cm-' respectively. While the hydroxyl group for virgin oil and waste cooking oil monomer is at 3423 cm-' and 341 1 cm-' respectively. The polymer formation for virgin oil and waste cooking oil was confirmed by its functional group of NH near 3340 cm-'and 3335 cm-' respectively. Result for tensile test of virgin oil polymer and waste cooking oil polymer is 0.42 MPa and 1.34 MPa respectively. Waste cooking oil polymer is 69 % higher compared to the virgin oil polymer. While the average value of elongation of waste cooking oil polymer is 67 % and virgin oil polymer were 15 %. The percentage elongation of waste cooking oil polymer is 78 % higher than virgin oil polymer. SEM microstructure is used to revealed the surface fracture of materials after tensile test. From the SEM microstructure, its shows virgin oil polymer have brittle surface and waste cooking oil polymer shows ductile and brittle surface.
