摘要： The heat resistant adhesive of the invention comprises polyamic acid and/or polyimide which are prepared by using 1,3-bis(3-aminophenoxy)benzene as an aromatic diamine component and 3,3′, 4,4′-biphenyltetracarboxylic dianhydride, 3,3′,4,4′-benzophenonetetracarboxylic dianhydride and/or 3,3′,4,4′-diphenylethertetracarboxylic dianhydride as tetracarboxylic acid dianhydrides, and further by blocking the polymer chain end with dicarboxylic anhydride or a monoamine compound ; or comprises a polyimide solution containing the polyimide in a good solvent. The adhesive of the invention is a heat-resistant adhesive capable of adhering under mild temperature/mild pressure conditions. The adhesive of polyimide solution can provide desired adhesion by simple procedures such as applying to the adherend and heating under pressure and exhibits excellent adhesive strength. Consequently, the heat-resistant adhesive of the invention is very useful for the adhesion of structural and electronic materials and other industrial materials.

摘要： This invention relates to a process for preparing polyimide having good heat-stability and excellent flowability in a molten state. The polyimide is prepared by reacting 3,3′-diaminobenzophnone or bis(3-aminophenyl)sulfone, tetracarboxylic dianhydrides such as pyromellitic dianhydride, 3,3′,4,4′-benzophenonetetracarboxylic dianhydride and bis(3,4-dicarboxyphenyl) ether dianhydride; and dicarboxylic anhydrides such as glutaric anhydride, 1,2-hexanedicarboxylic anhydride, phthalic anhydride and 3,4-benzophenonedicarboxylic anhydride. The molar ratio of aromatic diamine : tetracarboxylic dianhydride : dicarboxylic anhydride is 1 :(0.9 to 1.0) : (0.001 to 1.0).
