Title:
アントラキノン誘導体テトラアミンモノマー、それに由来する真性黒色ポリイミド及びその調製方法
Document Type and Number:
Japanese Patent JP7345806
Kind Code:
B2
Abstract:
To provide an intrinsic black polyimide that has good light shielding performance and excellent mechanical properties, thermal stability, and dielectric properties.SOLUTION: An anthraquinone derivative tetraamine monomer has a structure represented by following General formula I. Only two amine groups of the present anthraquinone derivative tetraamine monomer can undergo a polycondensation reaction, so a linear polymer can be obtained. Intrinsic black polyimide obtained from anthraquinone derivative tetraamine monomer has good light-shielding performance, excellent mechanical properties, thermal stability, and dielectric properties, and has a light transmittance in all wavelength bands of less than 1%.SELECTED DRAWING: Figure 3
