Vorschrift

Poly(p-hydroxystyrene) (VP-2500, produced by Nippon Soda Co., Ltd.) (30 g) as a polyhydroxystyrene compound was dissolved in 120 g of PGMEA (propylene glycol monomethyl ether acetate). To this solution, 10.40 g of 2-cyclohexylethyl vinyl ether as a vinyl ether compound and 1.45 g of 2 mass % comphorsulfonic acid (PGMEA solution) were added thereto, and the mixture was stirred at room temperature for 2 hours. Furthermore, 1.05 g of 10 mass % triethylamine (PGMEA solution) was added and after stirring for a while, the reaction solution was transferred to a separating funnel containing 165 mL of ethyl acetate. The organic layer was washed with 200 mL of distilled water three times, and ethyl acetate was removed in an evaporator. The obtained reaction solution was added dropwise to 2 L of hexane, and the supernatant was removed. The obtained product was dissolved in 95 g of PGMEA, and the low-boiling-point solvent was removed under reduced pressure conditions to obtain 132.3 g of a PGMEA solution (28.3 mass %) of Polymer Compound (R-11).
