Inhibitor was removed from p-methylstyrene (p-MS) (Acros Organics) by passing through a column of basic alumina. The monomers p-MS (3 mL, Aldrich) and BP (0.45 g) were polymerized in 30 mL of 1,4-dioxane at 80◦C for 15 h under nitrogen following three freeze–pump–thaw cycles, resulting in a copolymer containing 10 mol% of BP. The polymer was purified by precipitation into methanol, washed under vacuum filtration and dried overnight in a vacuum oven prior to use. Structure was confirmed by 1H NMR
