실험 절차

Using p-tert-butoxystyrene (3.5 g, 0.02 mole) and p-hydroxystyrene (2.7 g, 0.02 mole), free radical polymerization was carried out in the same manner as described in Synthesis Example 1. Then, the reaction mixture was poured into petroleum ether, and the precipitate was filtered, washed and dried in vacuo to give 5.0 g of the title compound as a white powder having Mw 10000 (GPC with polystyrene calibration). The composition of the polymer was found to be p-tert-butoxystyrene and p-hydroxystyrene in a molar ratio of ca. 1:1 based on 1HNMR analysis.
