Abstract: PROBLEM TO BE SOLVED: To manufacture a wiring board having a high density three- dimensional wiring structure from which such a defect as conduction between metal wiring members is eliminated by placing a plurality of metal wiring members in a die and integrating them by filling the die with a resin molding material. SOLUTION: Polyethylene terephthalate/polyethylene isophthalate copolymer powder is placed in a hydraulic bath and a stainless plate is suspended therein. A coating is formed entirely on the surface of the stainless plate except the plate end part. A plurality of stainless plates are then set in a die and PBT resin is insert molded. When 1000 moldings thus produced are checked for conduction between respective terminals, conduction is detected in two moldings between terminals other than identical planar terminals (A-A', B-B', C-C', D-D', E-E', F-F') in the voltage range of 100-2000 V. In other words, a highly reliable three-dimensional wiring can be formed by single insert molding.

Abstract: PROBLEM TO BE SOLVED: To obtain a resin excellent in viscosity stability while kept in a molten state by anion-polymerizing lactams using a basic catalyst and then heating it under passage of an inert gas or under a reduced pressure thereby volatilizing and removing oligomers and/or unreacted lactams and the basic catalyst. SOLUTION: A raw material composition comprising lactams and a basic catalyst is heated in polymerization usually at a temperature of not lower than 50 deg.C and not higher than 330 deg.C. The volatilization for removal of oligomers and/or unreacted lactams and the basic catalyst is carried out usually at a temperature of not lower than 130 deg.C and not higher than 400 deg.C. As inert gases can be employed steam, nitrogen, argon or carbon dioxide, and preferably steam and nitrogen. The heating under a reduced pressure is carried out usually at a pressure not higher than 500 mmHg. Usually, as the basic catalysts, organic basic catalysts are preferably employed. The organic basic catalysts are preferably nitrogen-containing compounds and more preferably those compounds containing both nitrogen and phosphor.

Abstract: PROBLEM TO BE SOLVED: To produce a high-quality polyamide by a high-production-efficiency low- energy-cost production process which can be dispensed with a step of extracting unreacted lactam or oligomers with hot water and a drying step which have heretofore been indispensable in industrially producing a polyamide from a caprolactam. SOLUTION: A polyamide having an unreacted lactam content of 0-0.5 wt.% an oligomer content of 0-1.25 wt.%, and a relative viscosity of 2.2-8.0 (in a sulfuric acid solution at 25 deg.C) is produced by the first step of producing a polymer product having an unreacted lactam content of 25 wt.% or below and an oligomer content of 0-1.8 wt.% by polymerizing a caprolactam-based polymerizable material at atmospheric pressure and the second step of removing unreacted lactam and oligomers from the obtained polymer product by heating it in a vacuum at a temperature T falling in the range: Tg of the polyamide
