Reaction Steps
To 400 mL of isopropanol, 87.7 g of p-hydroxystyrene, 18.7 g of styrene and 18.6 g of 1-adamantyl acrylate were dissolved, then 10.0 g of 2,2′-azobis(methyl 2-methylpropionate) (V-601: trade name of a product from Wako Pure Chemicals Ind., Ltd.) was added and the solution reacted at 80° C. for 6 hours under nitrogen gas flow. After the reaction, said reaction liquid was poured into 10 L of water for precipitation, followed by filtering off deposited crystal, drying under reduced pressure, to obtain 100 g of poly(p-hydroxystyrene/styrene/1-adamantyl acrylate) as a pale brown powder crystal. The copolymer obtained was named polymer 3. A composition ratio of p-hydroxystyrene unit, styrene unit and 1-adamantyl acrylate unit in polymer 3 was found to be about 73:18:9 from the measurement results by 13CNMR. Weight average molecular weight (Mw) of this copolymer was about 9,800 and distribution (Mw/Mn) thereof was about 1.80 from the measurement results by gel permeation chromatography using polystyrene as a standard.
