    摘要: A heat resistance resin composition having superb low-temperature adhesiveness and a polyimide/metal laminate which is superior in solder heat resistance and hardly generates swelling when forming a AunullSn bond or AunullAu bond, which are used for lead-free soldering and COF packaging. A metal laminate comprising a layer comprises a resin composition prepared by compounding a bismaleimide compound represented by the following formula (1) in a polyamic acid and/or a polyimide: 1 wherein m denotes an integer of 0 or more, each X independently represent O, SO2, S, CO, CH2, C(CH3)2, C(CF3)2 or a direct bond and each R1 independently represents a hydrogen atom, a halogen atom or a hydrocarbon group and is independent of any other R1 as to the substitution position on the benzene ring; and a metal foil layer, wherein the layer of the resin composition is formed on at least one surface of the metal foil layer. A resin composition for a metal laminate is also disclosed.

    摘要: A bis(disubstitutedmaleimide) derivative and a polyetherimide for optical communications and the polyetherimide formed therefrom are described. The polyetherimde has a high refractive index, so that when using such polyetherimide as a material for a core of an optical fiber, the range of the materials that can be selected for the cladding becomes wide. Also, a coating property and adhesion to a substrate are improved, thereby providing a good film forming property and thermal stability. Also, because the polyetherimide can minimize optical loss at a near infrared wavelength range, the polyetherimide is very useful as an optical material in the optical communications field adopting the light of near infrared wavelength.

    摘要: The present invention provides an optical film exhibiting wavelength dispersion such that a retardation value is smaller on the shorter wavelength side, and capable of being also formed comparatively thinly.The optical film of the present invention is an optical film including a polyimide-based polymer represented by the following general formula (I).In the formula (I), m is 40% by mol or more and 100% by mol or less. R1 and R2 each independently denote a substituent having a carbon-carbon double bond or a triple bond. A, A′, B, B′, E, G, and H each denote a substituent, and small letters corresponding to these alphabets denote substitution number thereof. X and Y each independently denote bond part such as a covalent bond. The substituents having a carbon-carbon double bond or a triple bond represented by R1 and R2 are a substituted or unsubstituted aryl group, a substituted or unsubstituted vinyl group, and a substituted or unsubstituted ethynyl group.

    摘要: Copolymers of polycarbonates or polyarylates with polyether polymers such as polyethersulfones, polyetherketones, and polyetherimides are prepared by reaction of the polyether polymer-forming reagents, e.g., bisphenol A disodium salt and bis(4-chlorophenyl) sulfone, in the presence of the polycarbonate or polyarylate. The reaction may take place in a dipolar aprotic solvent, or in a water-immiscible aromatic solvent in the presence of a phase transfer catalyst, preferably a hexaalkylguanidinium halide. Hydroxy-terminated polyether oligomers may be produced from the copolymers by saponification of carbonate or ester groups.
