실험 절차
In 40 ml of pyridine was dissolved poly(p-hydroxystyrene) (VP-8000, manufactured by Nippon Soda Co., Ltd., weight average molecular weight: 11,000) and to the solution was added 1.28 g of di-tert-butyl dicarbonate at a room temperature with stirring. The solution was reacted at a room temperature for 3 hours and poured into a solution of one liter of ion-exchanged water and 20 g of concentrated hydrochloric acid. The powder thus-deposited was collected by filtration, washed with water and dried to obtain p-hydroxystyrene/p-(tert-butoxycarbonyloxy)-styrene (60/40) copolymer. The Mw of the resin was 12,000 and the molecular weight distribution (Mw/Mn) thereof was 1.1.
