## Abstract MgCl~2~/TiCl~4~/SiO~2~ catalysts were prepared by treating TiCl~4~/SiO~2~ with MgCl~2~ Β· 2THF (THF: tetrahydrofuran) at different Mg/Ti ratios. The catalysts were analysed by X‐ray, electron spin resonance (ESR), atomic absorption spectrometry to determine the crystal structure, oxidati
