Patent ID: 8420289

Claim:
An aromatic ring-containing polymer, comprising: at least one aromatic ring-containing polymer represented by Formulae 1, 2, or 3: wherein in Formula 1, R 1 is hydrogen, hydroxyl (—OH), C 1 -C 10 alkyl, C 6 -C 10 aryl, allyl, or halogen, R 2 is hydroxyl (—OH), amino (—NH 2 ), —OR (R is C 1 -C 10 alkyl or C 6 -C 10 aryl), or —NRR′ (R and R′ are each independently C 1 -C 10 alkyl or C 6 -C 10 aryl), R 3 is —CH 2 —, and m satisfies the relation: 1 ≦m<190, in Formula 2, R 1 and R 4 are each independently hydrogen, hydroxyl (—OH), C 1 -C 10 alkyl, C 6 -C 10 aryl, allyl, or halogen, R 2 and R 5 are each independently hydroxyl (—OH), amino (—NH 2 ), —OR (R is C 1 -C 10 alkyl or C 6 -C 10 aryl), or —NRR′ (R and R′ are each independently C 1 -C 10 alkyl or C 6 -C 10 aryl), R 3 and R 6 are each independently —CH 2 and m and n satisfy the relations: 1≦m<190, 1≦n<190, and 2≦m+n<190, and in Formula 3, R 1 is hydrogen, hydroxyl (—OH), C 1 -C 10 alkyl, C 6 -C 10 aryl, allyl, or halogen, R 2 is hydroxyl (—OH), amino (—NH 2 ), —OR (R is C 1 -C 10 alkyl or C 6 -C 10 aryl), or —NRR′ (R and R′ are each independently C 1 -C 10 alkyl or C 6 -C 10 aryl), R 3 and R 8 are each independently —CH 2 and m and o satisfy the relations: 1≦m<190, 1≦o<190, and 2≦m+o<190.
