Abstract: 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).

Abstract: The invention relates to molding resin compositions, and more particularly relates to polyimide resin compositions having markedly improved molding ability in addition to excellent high temperature stability, chemical resistance and mechanical strength. The polyimide resin compositions of this invention consist of 99.9 to 50% by weight of the polyimide and 0.1 to 50% by weight of high-temperature engineering polymer. The polyimide consists of recurring units of the following formula: wherein X is direct bond, thio radical, or o- or p-phenylene dicarbonyl radical and R is a tetravalent radical selected from an aliphatic radical, alicyclic radical, monoaromatic radical, condensed aromatic radical and non-condensed aromatic radical. R is, for example, The high-temperature engineering polymer is, for example, polyphenylene sulfide consisting of recurring units of the formula: aromatic polysulfone consisting of recurring units of the formula: or aromatic polyetherimide consisting of recurring units of the formula:

Abstract: POLYIMIDE AND HIGH-TEMPERATURE ADHESIVE OF POLYMIDE This invention relates to a novel polyimide and describes method of its preparation, adhesives of the polyimide and the method for their application. The polyimide has recurring units of the formula (where R is a tetra-valent radical selected from the group consisting of aliphatic radical having not less than two carbons, cyclo-aliphatic radical, monoaromatic radical, condensed polyaromatic radical, and non condensed polyaromatic radical wherein aromatic radicals are mutually connected with a bond or a crosslinking function). The polyimide can be prepared by reacting 2,6-bis(3-amino-phenoxy)pyridine with tetracarboxylic dianhydride in an organic solvent and imidizing resultant polyamic acid. Various tetracarboxylic dianhydrides can be used and particularly prefered are pyromellitic dianhydride and 3,3',4,4'benzophenonetetracarboxylic dianhydride.
