Abstract: A substrate for an electronic device having high carrier transport ability, a method for manufacturing a substrate for an electronic device which can manufacture such a substrate for an electronic device, an electronic device provided with the substrate for an electronic device and having improved properties, and electronic equipment having high reliability are provided. A substrate for an electronic device includes a light emitting layer (organic semiconductor layer), a cathode (inorganic layer), and an intermediate layer provided between the light emitting layer and the cathode so as to make contact with both of the light emitting layer and the cathode. The intermediate layer is constituted of a compound (1) represented by a general formula R—X—O-M as a main component thereof. In the general formula, the R is a hydrocarbon group, the X is any one of binding groups comprising a single bond, a carbonyl group and a sulfonyl group, and the M is any one of a hydrogen atom and a metal atom.

Abstract: Disclosed is a polymeric material obtained by melt-kneading, using a kneading apparatus, a resin composition containing an organic polymer having no metal alkoxy group and a metal alkoxide compound. The organic-inorganic hybrid polymeric material, a polymeric material containing this component, and a molded products obtained therefrom are suitable for high-performance and high-function plastic applications. Simple and practical processes for producing them at high productivity and at low cast are also disclosed.

Abstract: A process for making a high molecular weight, extended &pgr;-conjugated polymer from a monomer comprising a heterocyclic, benzylic or phenolic ring is described.

Abstract: New compositions, metal-ligand complexes and arrays are disclosed that catalyze the polymerization of monomers into polymers.

Abstract: Copolymers of sulfur dioxide and/or carbon monoxide and olefins, especially ethylene, can be made by contacting these monomers with a combination of selected strong Lewis acid and a selected metal or a compound of a selected metal. The resulting polymers, which are often alternating copolymers, are useful as molding resins.

Abstract: Disclosed herein is a process for the production of a polyarylenesulfide, wherein an alkali metal sulfide is reacted with a dihalo-aromatic compound in an organic amide solvent. The process comprises causing at least one compound selected from the oxides and hydroxides of alkaline earth metals to exist in a proportion not less than 0.01 mole but less than 0.1 mole per mole of the alkali metal sulfide charged in the reaction system, and performing the reaction of the alkali metal sulfide and dihalo-aromatic compound while raising the temperature by at least two stages in the presence of water in an amount defined in a specific range. A high-molecular weight linear polyarylenesulfide can be provided without use of a crosslinking agent or a polymerization aid.
