Abstract: PURPOSE:To obtain a polyimide excellent in heat resistance, processability and high-temperature adhesiveness, having specified repeating units and pyridine rings in the main chain skeleton. CONSTITUTION:A polyimide having repeating units of formula I and having a logarithmic viscosity of 0.1-3.0dl/g as measured in the form of a polyamic acid, as a precursor thereof, having repeating units of formula II. In the formulas, R is a tetravalent group selected from among a 2C or higher aliphatic group, a cycloaliphatic group, a mononuclear aromatic group, a condensed polynuclear aromatic group and a noncondensed polycuclear aromatic group composed of aromatic groups connected with each other directly or through a bridging member. Said relative viscosity is a value as determined in N,N- dimethylacetamide solvent at a concentration of 0.5g/100ml of the solvent and 35 deg.C. This polyimide can be used in a wide variety of fields such as a base material for use in aerospace and aircraft, a base material for electrical and electronic products, a heat-resistant adhesive as well as a polymeric material for medical use and a material for separatory membranes.

Abstract: PURPOSE:To obtain a circuit board having all good heat resistance, electrical characteristic, adhesive property, mechanical characteristic, e.g. flexibility, and dimensional stability, by laminating a metal foil to a thermosetting polyimide film with a specific polyimide film as an adhesive. CONSTITUTION:A polyimide film produced by reacting a symmetric aromatic primary amine group containing a symmetric aromatic meta-substituted primary amine at 100-20% equivalent ratio with an aromatic tetracarboxylic acid anhydride is used as an adhesive in laminating a metal foil to a thermosetting polyimide film. The formed polyimide film is inserted between a film without adhesive property and a metal foil to laminate both film and foil while heating under pressure. The above-mentioned formed film is used as both an adhesive and an insulating layer for lamination.

Abstract: PROBLEM TO BE SOLVED: To provide a polyimide resin compsn. which has a high rate of crystallization by comprising a polyimide having a repeating unit represented by a particular formula and a crystallization accelerator of a bismaleimide compd., an imide oligomer, or a bismaleimide mixture. SOLUTION: 4,4'-Bis(3-aminophenoxy)biphenyl is reacted with pyromellitic acid dianhydride to prepare a crystalline polyimide comprising a repeating unit represented by formula I. A crystalline polyimide in an amt. of 100 pts.wt. (hereinafter referred to as 'pts.') is mixed with at least one crystallization accelerator, in an amt. of l to 50 pts.wt., selected from among a bisimide compd. and the like represented by formula II (wherein X represents formula III; and Y1 represents formula IV), an imide oligomer represented by formula V (wherein (n) is 1 to 3), and a mixture of bisimide compds. represented by formulae VI and VII (wherein Z2 represents H, CH3 , C2 H5 or the like). This mixture is melt- kneaded by means of a melt mixer or the like at about 390 to 420 deg.C to prepare a polyimide resin compsn. for molding which can markedly shorten the cooling time for melt molding.
