    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 novel polyimide which is high-temperature resistant and capable of being molded in a fused state. This invention also relates to a high-temperature adhesive using the polyimide.The polyimide consists essentially of recurring units of the formula: ##STR1## where R is a tetra-valent radical selected from the group consisting of an aliphatic radical having 2 or more carbon atoms, alicyclic radical, monoaromatic radical, condensed polyaromatic radical, and non-condensed polyaromatic radical wherein aromatic radicals are linked to one another directly or via a bridge member.The polyimide can be prepared by reacting bis[4-(4-aminophenoxy)phenoxy)phenyl] sulfone with a tetracarboxylic dianhydride in an organic solvent and imidizing the resultant polyamic acid.Various tetracarboxylic dianhydrides can be used and preferred dianhydride are pyromellitic dianhydride, 3,3',4,4'-benzophenonetetracarboxylic dianhydride, bis(3,4-diarboxyphenyl) ether dianhydride, 3,3',4,4'-biphenyltetracarboxylic dianhydride, and 4,4'-(p-phenylenedioxy)diphthalic dianhydride.
