practical polyethylene synthesis was discovered (again by accident) in 1933 by Eric Fawcett and Reginald Gibson at the ICI works in Northwich‚ England.[6] Upon applying extremely high pressure (several hundred atmospheres) to a mixture of ethylene and benzaldehyde they again produced a white‚ waxy‚ material. Because the reaction had been initiated by trace oxygen contamination in their apparatus the experiment was‚ at first‚ difficult to reproduce. It was not until 1935 that another ICI chemist‚ Michael

The 2-naphthol (4.33 g‚ 0.03 mol) was dissolved in 30ml of ethanol and it was mixed with N-methylpiperizine (3.0 mL‚ 0.03 mol) by continuous stirrer at room temperature until a clear solution was obtained. The benzaldehyde (3.0 mL‚ 0.03 mol) was added slowly to this mixture with constant stirring. After 48 hours of continuous stirring‚ a white color precipitate was formed and it was washed with distilled water several times and dried in the air oven at 60 °C. The
