Procedure

Poly (p-hydroxystyrene) (VP-8000, manufactured by Nippon Soda Co., Ltd., weight average molecular weight: 11,000) was dissolved in 40 ml of pyridine, and 1.28 g of di-t-butyl dicarbonate was added to the solution with stirring at room temperature. After performing the reaction at room temperature for 3 hours, the reaction solution was poured into 1 liter of ion exchange water containing 20 g of concentrated hydrochloric acid. The powder precipitated was filtered, washed with water, and dried, thereby p-hydroxystyrene/p-(t-butyloxycarbonyloxy)styrene copolymer (60/40) was obtained.
