Claims20
A poly(amide-imide) copolymer that is a reaction product of;
- a diamine comprising a compound represented by Chemical Formula 1,
- a tetracarboxylic acid dianhydride comprising a compound represented by Chemical Formula 2, and
- a compound represented by Chemical Formula 3:
- wherein in Chemical Formula 1,
- R1 is a halogen-substituted C1 to C10 alkyl group;
- wherein in Chemical Formula 2,
- R2 and R3 are each independently hydrogen, or a halogen-substituted or an unsubstituted C1 to C10 alkyl group;
- wherein, in Chemical Formula 3,
- R4 is a substituted or unsubstituted phenylene group or a substituted or unsubstituted biphenylene group, and
- each X is an identical or a different halogen atom.
A composition for preparing a poly(amide-imide) copolymer comprising a compound represented by Chemical Formula 1, a compound represented by Chemical Formula 2, and a compound represented by Chemical Formula 6:
- wherein in Chemical Formula 1,
- R1 is a halogen-substituted C1 to C10 alkyl group;
- wherein in Chemical Formula 2,
- R2 and R3 are each independently hydrogen, or a halogen-substituted or an unsubstituted C1 to C10 alkyl group;
- wherein, in Chemical Formula 6,
- n0 is an integer of greater than or equal to 1,
- R4 is a substituted or unsubstituted phenylene group or a substituted or unsubstituted biphenylene group, and
- Ar1 and Ar2 are, each independently, represented by Chemical Formula 7:
- wherein, in Chemical Formula 7,
- R8 and R9 are each independently —CF3, —CCl3, —CBr3, —Cl3, —NO2, —CN, —C(═O)CH3, and —CO2C2H5, and
- n3 and n4 are each independently an integer ranging from 1 to 4.
