摘要： PROBLEM TO BE SOLVED: To obtain a thermosetting polymer exhibiting excellent heat resistance, electrical characteristics, such as a low dielectric constant, and low water absorption, which are necessitated as electric and electronic materials, and useful as wiring base materials, etc., by subjecting a specific phenol and a diethynyl compound to oxidative coupling. SOLUTION: This thermosetting polymer is obtained by subjecting (A) 70-95 mol% of 2,6-diphenylphenol expressed by the formula and (B) 5-30 mol% of a diethynyl compound expressed by the formula: CH≡C-Ar-C≡CH (Ar is a divalent aromatic unit) (for example, m-diethynylbenzene) to oxidative coupling polymerization at 40-110 deg.C, and has a weight-average molecular weight of 2,000-500,000 when measured by gel permeation chromatography. The component B is added, for example, in an amount of 5-30% based on the total amount of the component A and component B. The polymerization is preferably performed in the presence of a copper compound/amine-based catalyst in a solvent, such as toluene.

As the conductive filler, conductive metal such as silver and gold is used. The amount of the conductive filler is limited to 70-95wt.%, and the amount of the thermoplastic resin in the total resin of the thermoplastic resin and the thermosetting resin is limited to 3-97wt.%. The conductivity and adhesion ability are satisfied at the same time, and by heating at a temperature of glass transition temperature or higher or treating with a solvent, an adhesive is easily made reusable.

摘要： PROBLEM TO BE SOLVED: To easily obtain a uniform porous silicon dioxide film adhering tightly to the substrate, free from cracks and not causing peeling by filmily coating the top of a surface-modified substrate with a soln. prepd. by mixing alkoxysilane with an amido bond-contg. org. polymer, water and a catalyst, carrying out hydrolysis and dehydration condensation and removing the org. polymer from the resultant dry gel. SOLUTION: The top of a substrate surface-treated with an adhesion improver such as a silane coupling agent is filmily coated with a soln. prepd. by mixing alkoxysilane with an amido bond-contg. org. polymer such as poly (N- vinylpyrrolidone) or a polyacrylamide deriv., water and a catalyst. The alkoxysilane is then subjected to hydrolysis and dehydration condensation and the org. polymer is removed from the resultant dry gel to obtain the objective porous silicon dioxide film. The org. polymer is easily removed from the dry gel film by heating at a temp. above the thermal decomposition temp. of the polymer for about 1-24hr.
