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.

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 min -diaminobenzophnone or bis(3-aminophenyl)sulfone, tetracarboxylic dianhydrides such as pyromellitic dianhydride, 3,3 min ,4,4 min -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: A process for the production of polyimide fibers and polyimide fibers obtained by the process. The process includes thermal or chemical imidation of a polyamic acid which has been obtained by reacting a specific diamine and a particular tetracarboxylic dianhydride in the presence of a dicarboxylic anhydride represented by the following formula: wherein Z represents a divalent group selected from the group consisting of monocyclic aromatic groups, fused polycyclic aromatic groups and non-fused polycyclic aromatic groups with aromatic rings bonded together directly or via a crosslinking member.
