| 摘要 |
The present invention relates to a imide-based polymer, as a co-monomer of carbonate copolymer and, more specifically, to a imide-based polymer, which is greatly compatible with bisphenol-A, which is carbonate copolymer, is excellent in solubility in organic solvent, and presents excellent flame resistance and durability when becoming copolymer, as a co-monomer of carbonate copolymer. The 1-10 wt% of imide-based polymer provided in the present invention is used with respect to carbonate copolymer when copolymerizing with polycarbonate, and the desirable amount is 1-5 wt%. When the weight percentage is over 10, transparency of copolymerized polycarbonate and polyimide decreases, and total yield decreases due to degradation of miscibility. When using the imide-based polymer provided in the present invention, excellent impact strength, flame resistance and transparency can be obtained. |
