Abstract: 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: 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-(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 min ,4,4 min -benzophenonetetracarboxylic dianhydride, bis(3,4-dicarboxyphenyl) ether dianhydride, 3,3 min ,4,4 min -biphenyltetracarboxylic dianhydride, and 4,4 min -(p-phenylenedioxy)diphthalic dianhydride.

Abstract: HIGH-TEMPERATURE ADHESIVE OF POLYIMIDE This invention discloses high-temperature adhesives having a good light-transmittance and excellent high-temperature flowability which comprises polyimide having recurring units represented by the following formula (I) (I) (where R is a tetra-valent radical selected form 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 is obtained by preparing polyamic acid through the reaction of 2,2-bis¢4-(3-aminophenoxy)phenyl!-1,1,1,3,3,3,-hexafluoropropane as a diamine component with tetracarboxylic dianhydride such as pyromellitic dianhydride, 3,3',4,4'biphenyltetracarboxylic dianhydride, bis(3,4-dicarboxyphenyl) ether dianhydride and 3,3'4,4'-benzophenonetetracarboxylic dianhydride, and further conducting the ring-closing reaction of resultant polyamic acid by dehydration.

Abstract: POLYIMIDE FOR HIGH-TEMPERATURE ADHESIVE 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 the positions of two carbonyl radicals in a benzene ring are meta or para, and 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 diamine with tetracarboxylic dianhydride in organic solvents and imidizing resultant polyamic acid. The diamine in use is ether diamine and includes 1,3-bis¢4-(3-aminophenoxy)benzoyl!benzene and 1,4-bis¢4-(3-amino-phenoxy)benzoyl!benzene. 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 method for preparing polyimide having good heat-stability and excellent flowability in a molten state. The polymide is prepared by reacting aromatic diamines such as 4,4 min -bis(3-aminophenoxy)biphenyl, bis[4-(3-aminophenoxy)phenyl] ketone and bis [4-(3-aminophenoxy)phenyl] 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). Another invention relates to polyimide composite materials which are excellent in mechanical strengths and processability. The materials contain the polyimide and fibrous reinforcing materials such as yarn, roving, tow, fabrics, mats and felts of glass fiber, carbon fibers or aromatic polyamide fibers.
