実験手順

In 100 mL of acetone were dissolved 16.2 g of poly(p-hydroxystyrene) and isopropyl chloride. To this reaction mixture was added 1.8 g of triethylamine. This mixture was stirred at 50 to 55° C. for 5 hours. The resultant reaction mixture was transferred to 1,000 mL of water, and the upper layer was removed by decantation. The viscous resinous substance obtained was dissolved in 75 mL of acetone, and this solution was transferred to 500 mL of water. The rubbery resin precipitated was dried under vacuum. Thus, 15.4 g of poly(p-hydroxystyrene/p-isopropoxystyrene) was obtained as a white powder.
