| 摘要 |
The present invention relates to a crosslinked water-soluble thermoplastic polyamic acid which can be used in the preparation of a heat-welding multilayer polyimide film for a double-sided flexible copper clad laminate (FCCL) interlayer insulation material, and a method for preparing the same. The crosslinked water-soluble thermoplastic polyamic acid of the present invention can be coated using water as a diluting solvent, instead of expensive toxic organic solvents, and thus can be inline-coated in a safe, environment-friendly, and economical manner, without danger of explosion caused by oil mist. |
