## Abstract A supported metallocene catalyst was synthesized by sequentially loading methylaluminoxane (MAO) (30 wt % in toluene) and (^__n__^BuCp)~2~ZrCl~2~ on partially dehydroxylated silica ES 70 modified by ^__n__^BuSnCl~3~. Its shock load hydrogen responsiveness was evaluated by polymerizing e
