실험 절차

In one typical embodiment, the polymer can be synthesized by dissolving an acetoxystyrene monomer, a tertiary alkyl (meth)acrylate monomer and an indene monomer in an organic solvent, adding a radical initiator thereto, heat polymerizing the monomers, and subjecting the resulting polymer to alkaline hydrolysis in an organic solvent for deblocking the acetoxy group, thereby forming a ternary copolymer of hydroxystyrene, tertiary alkyl (meth)acrylate and indene. Examples of the organic solvent used in polymerization include toluene, benzene, tetrahydrofuran, diethyl ether, and dioxane. Representative of the polymerization initiator are 2,2′-azobisisobutyronitrile, 2,2′-azobis(2,4-dimethylvaleronitrile), dimethyl-2,2-azobis(2-methylpropionate), benzoyl peroxide and lauroyl peroxide. Polymerization may be effected by heating at about 50 to 80° C. The reaction time is usually about 2 to 100 hours, preferably about 5 to 20 hours. The base used in the alkaline hydrolysis is selected from aqueous ammonia and triethylamine, to name a few. The reaction temperature is about −20° C. to 100° C., preferably about 0 to 60° C. The reaction time is usually about 0.2 to 100 hours, preferably about 0.5 to 20 hours.
