实验过程

208 g of 9-anthracene methanol (1 mol), 309 g of dicyclohexyl carbodiimide (1.5 mol) and a methacrylic acid were stirred and dissolved in 2,000 g of a THF solution to form a preliminary mixture. 183 g of 4-dimethyl amino pyridine (1.5 mol) was injected into the preliminary mixture at a temperature of 0° C. to obtain a mixture. The mixture was stirred at room temperature for 6 hours. A solvent was then removed from the stirred mixture. The mixture without the solvent was repeatedly re-crystallized using methanol to obtain 163 g of an anthracene methacrylate monomer. 82 g of the anthracene methacrylate monomer, 34 g of p-tert-butoxystryne and 43 g of methacrylic acid were dissolved in 380 g of propylene glycol monomethyl ether acetate (PMA) to obtain a polymerization mixture. The polymerization mixture was heated at a temperature of 60° C. for 2 hours under a nitrogen atmosphere to synthesize a preliminary copolymer resin. 1 l of n-hexane was injected into the preliminary copolymer resin to remove non-polymerized portions from the preliminary copolymer resin, thereby synthesizing 120 g of copolymer resin. Here, the copolymer resin had a weight-average molecular weight of 5,600 and a dispersion degree of a molecular weight distribution of 2.4.
