Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a molded member under the condensation of a polyamide molding material whose polyamide component contains phosphorus in an amount of at least 5 ppm limited by the production in the form of an acidic compound, with a compound having at least two carbonate units. SOLUTION: This method for producing the molded member is characterized by (a) adding a weak acid salt in an amount of 0.001 to 10 mass% based on the polyamide to the polyamide molding material, before or when compounded, (b) producing a mixture of the completed compound with a compound having at least two carbonate units, (c), if necessary, storing and/or transporting the mixture, and (d) then processing the mixture into the molded member, wherein a condensation is carried out for the first time in the process. According to the present invention, a middle processing pressure, a slight motor load, and the remarkable increase of melt stiffness are caused to considerably simplify the production of a hollow article or hollow deformed article having a large diameter.

Abstract: PROBLEM TO BE SOLVED: To provide a method by which a large producible geometrical shape article can economically be produced without being limited by the melt stiffness of a polyamide used herein. SOLUTION: This method for producing the molded member, while condensing a polyamide molding material with a compound having at least two carbonate units, is characterized by (a) preparing the polyamide molding material, (b) producing a mixture of the polyamide molding material with the compound having at least two carbonate units, (c), if necessary, storing and/or transporting the mixture, and (d) then processing the mixture into the molded member, wherein the condensation is carried out for the first time in the process, and the molded article is a hollow article or hollow deformed article having a diameter of at least 30 mm and a thickness of at least 1 mm.

Abstract: PROBLEM TO BE SOLVED: To obtain a polyester molding material having a remarkably reduced melting viscosity or improved flowability, without extremely deteriorating mechanical characteristics of the molding material. SOLUTION: In the molding material comprising (a) 95-99.5 pts. by mass of a thermoplastic aromatic polyester and (b) 5-0.5 pts. by mass of a monocarboxylic acid, the sum of the (a) and the (b) being 100 pts. by mass, the molding material further contains (c) a filler, a pigment, a reinforcer, an additive which imparts static electricity characteristic resistance or electrical conductivity to the molding material, a particulate, a stratified and/or a fiber shape additive selected between a nucleating agent and a particulate flame retardant, the additive being 0.5-60 pts. by mass on the basis of the molding material, the solution viscosity of the polyester which is incorporated in the molding material being 50-80 cm 3 /g by a measurement as a J value according to DIN 53728/ISO 1628/Teil 5, and a melt index of the molding material being 12-60 cm 3 /10 min by a measurement as MVR at 250°C/5 kg.
