A 500 ml three-necked flask was charged with 79.3 g (0.36 mol) of 1-benzyloxyethyl methacrylate, 23.1 g (0.18 mol) of glycidyl acrylate, 7.8 g (0.06 mol) of 2-hydroxyethyl methacrylate and 300 ml of methyl isobutyl ketone. A catalytic amount of 2,2′-azobis(methyl 2-methylpropionate) as a radical polymerization initiator was added to the mixture, and polymerization was performed in a nitrogen stream at 80° C. for six hours. The obtained reaction liquid was cooled, and poured in a large volume of heptane, thereby precipitating a polymer. The polymer crystal was collected by filtration, and dissolved in diethylene glycol ethylmethyl ether. The heptane and methyl isobutyl ketone contained in the solution were distilled off in vacuum, thereby obtaining a diethylene glycol ethylmethyl ether solution of polymer A-3 (1-benzyloxyethyl methacrylate/glycidyl acrylate/2-hydroxyethyl methacrylate).
