The general approach to these compounds involved preparing the corresponding fluorobromobenzenes, converting them via Grignard reagents to the corresponding primary, secondary or terti-ary alcohols, and then dehydrating the alcohols to the desired styrenes. Careful studies were made of the dehydrating conditions in each case, since clear, hard polymers. All except the p-methylstyrene copolymerize with butadiene to give rubbers ...
