Starting with 2-hydroxydiphenylmethane (5) and/or 2-isopropylphenol (5a), the bromination reaction in the para-position to the hydroxyl group yielded the corresponding brominated compounds 6 and/or 6a (87% and 90% yields, respectively) after purification by silic[alpha]-gel column chromatography.
The numerical values presented in Table 1 indicate that the branched and brominated samples have a MW to IV ratio that is different from that of the linear pure polystyrene, suggesting that branching and bromination change the way in which the polymers coil in solution.
