Procedure

Using poly(p-hydroxystyrene) (4.0 g) [available from Maruzen Petrochemical Co., Ltd.: Mw ca. 20000] and benzylisopropenylether (4.2 g) [purchased from Tokyo Chemical Industry Co., Ltd.], the reaction and treatment were carried out in the same manner as described in Synthesis Example 2, to give 4.1 g of the desired product as a slightly yellow powder. The polymer was found to have p-(1-benzyloxy-1-methylethoxy)styrene unit and p-hydroxystyrene unit in a molar ratio of 4:6 based on 1HNMR.
