Precursor of copolyphthalocyanine-imide lattice, preparation, and the resultant lattice

摘要

Aromatic polyimide compositions, precursors of copolyphthalocyanine-imides, their manufacturing process and the resultant copolyphthalocyanine-imides, are described. These compositions may result for the reaction of 80 DEG -300 DEG C. of an aromatic tetra acid, diester-diacid, tetraester or dianhydride compound of formula: <IMAGE> with an aromatic amino-dinitrile <IMAGE> and optionally an aromatic diamine NH2-Ar-NH2. A subsequent heating at 200 DEG -300 DEG C. provides, by cross-linking, copolyphthalocyanine-imides, which are hardened resins, stable at 250 DEG -300 DEG C. in continuous use.
