COPOLYMER, RESIN COMPOSITION CONTAINING THE COPOLYMER, FILM AND PHASE DIFFERENCE FILM

摘要

A copolymer includes a fumaronitrile residue represented by following General Formula I and an aromatic vinyl monomer residue represented by following General Formula II:;;wherein, in General-Formula II, R1 is a hydrogen atom, a methyl-group or a phenyl-group, and R2 is a hydrogen atom or a substituted or unsubstituted aryl-group having 6 to 12 carbon atoms, and each of R3, R4, R5, R6 and R7 independently represents a hydrogen atom, a halogen atom, a hydroxy-group, an alkoxy-group having 1 to 4 carbon atoms, an acyloxy-group having 2 to 5 carbon atoms, a cyanomethyl-group, or an alkyl-group having 1 to 8 carbon atoms, and at least two of R2, R3 and R4 may be bonded to form a ring, and at least two of arbitrary substituents of R3, R4, R5, R6 and R7 may be bonded to form a ring.
