반응 단계

To a round bottom flask equipped with condenser, thermometer, an argon (Ar) inlet, and a magnetic stirrer bar, the following were added: 4-acetoxystyrene monomer (2.43 grams (g), 0.015 mole), t-butyl acrylate monomer (1.6 g, 0.0125 mole), 3-hydroxy-1-adamantyl methacrylate monomer (5.319 g, 0.0225 mole), 2,2′-azobis(2-methylpropionitrile) (AIBN)(0.328 g, 4% of total moles of monomers), and approximately 40 g of tetrahydrofuran (THF). The reaction mixture was stirred at room temperature and bubbled with Ar flow for 45 minutes before it was heated. The reaction was carried out overnight at 72° C. under an inert Ar atmosphere. The rest of the synthetic procedures are the same as Example 1, except approximately 5 g of concentrated NH4OH was used in deprotecting the acetoxy groups from acetoxystyrene repeat units to form hydroxyl styrene repeat units of the terpolymer.
