실험 절차
Di-t-butyl dicarbonate in an amount of 1.6 g was added to a solution containing poly(p-hydroxystyrene) [weight-average molecular weight: 11,000] in 40 ml of pyridine while stirring at room temperature. Therein, the reaction was run for 3 hours at room temperature, and the resultant solution was poured into a solution containing 20 g of conc. hydrochloric acid in 1 liter of ion-exchanged water. A powdery matter thus precipitated was filtered off, washed with water, and dried to give a p-hydroxystyrene/p-(t-butyloxycarbonyloxy)styrene (50/50) copolymer.
