| titleOfInvention | Copolymer and optical film using the same |
| abstract | The present invention provides a novel copolymer and an optical film using the copolymer, and the copolymer can be expected to be an optical film which has high phase difference even if the copolymer is a film and has excellent phase difference characteristics. A copolymer comprising a residual unit A represented by the general formula (1) and a residual unit B represented by the general formula (2), wherein，R 1 、R 2 Each independently represents hydrogen, cyano, ester (-O) OX 1 ) Amide (-O) N (X) 2 )(X 3 ) Or acyl (-C (═ O) X) 4 ) And does not include R 1 、R 2 And is simultaneously hydrogen, wherein X 1 ～X 3 Independently represents a linear alkyl group having 1 to 12 carbon atoms, a branched alkyl group having 1 to 12 carbon atoms, or a cyclic alkyl group having 3 to 6 carbon atoms, X 4 Represents a linear alkyl group having 1 to 12 carbon atoms, a branched alkyl group having 1 to 12 carbon atoms, or a cyclic group having 3 to 14 carbon atoms; r 3 ～R 7 Each independently represents hydrogen, a linear alkyl group having 1 to 12 carbon atoms, a branched alkyl group having 1 to 12 carbon atoms, a cyclic group having 3 to 14 carbon atoms, halogen, hydroxyl, carboxyl, nitro, cyano, or alkoxy (-OX) 5 ) Ester group (-C (═ O) OX 6 ) Amide (-O) N (X) 7 )(X 8 ) - (═ O) X), acyl group (-C ═ O) X 9 ) Amino (-N (X)) 10 )(X 11 ) Or sulfonyl (-SOOX) 12 ) Wherein X is 5 ～X 8 Independently represents a linear alkyl group having 1 to 12 carbon atoms, a branched alkyl group having 1 to 12 carbon atoms, or a cyclic alkyl group having 3 to 6 carbon atoms, X 9 ～X 12 Each independently represents hydrogen, a straight-chain alkyl group having 1 to 12 carbon atoms, a branched alkyl group having 1 to 12 carbon atoms, or a cyclic alkyl group having 3 to 6 carbon atoms; in addition, R 3 ～R 7 Optionally forming condensed ring structures with each other by adjacent substituents, wherein R 8 Represents an m-membered heterocyclic ring residue containing 1 or more heteroatoms or a 5-or 6-membered ring residue containing no heteroatoms, wherein R is 8 R in the general formula (1) is a 6-membered ring residue containing no hetero atom 3 ～R 7 Wherein any 1 or more of them represent a hydroxyl group, and m represents an integer of 5 to 10; the m-membered heterocyclic residue, the 5-membered heterocyclic residue, and the 6-membered heterocyclic residue optionally form a condensed ring structure. |
