(Prior art) Aromatic polysulfone resin has excellent mechanical, thermal, and electrical properties, so it is molded using various molding methods and used for mechanical parts, aircraft parts, electrical parts, etc. , used in a wide range of electronic parts, etc. Generally, molded products using aromatic polysulfone resin are small and often have complex shapes, so strict dimensional accuracy is required. In order to maintain dimensional accuracy, the molded product cannot be easily removed from the mold due to the inability to take a sufficient draft angle, or depending on the shape of the molded product, there are restrictions on the position and size of the ejector pin. For this reason, it has often been difficult to produce molded products using automatic take-out devices in recent molding industries.

Furthermore, aromatic polysulfone resin has a high viscosity when melted, so high pressure is required for molding, and it is also poor quality, so it has a lower molding shrinkage rate and a higher modulus of elasticity than crystalline resins. etc., the mold releasability is extremely poor. For this reason, during molding, mold release properties and moldability have been improved by applying a mold release agent to the mold or kneading a processing aid into the resin.

However, the method of applying a mold release agent to the mold does not impair the appearance of the molded product, lengthens the molding cycle, and may even reduce the mechanical strength of the molded product. Furthermore, when processing aids such as fatty acid ester compounds, polyethylene wax, and microcrystalline wax are incorporated, the molecular weight of the resin may be lowered, mechanical and thermal properties may be lowered, and the surface of the mold may be contaminated. There is also a method of mixing metal soap, fatty acid amide, or fatty acid bisamide with resin pellets, which have relatively good mold release and processing effects.
However, in this method, if the amount added is increased, the pellets will slip during molding, resulting in poor quantitative determination of the resin. Therefore, the amount added must be kept to a very small amount, and sufficient mold release and processing effects have not been achieved.

(Means for Solving the Problem) As a result of various studies on aromatic polysulfone resin molding materials that have excellent mold releasability and moldability, the present inventors have discovered that powdered or particulate additives have been developed. In addition to aromatic polysulfone resin, by using a melt-kneaded material as a molding material, the mold releasability and molding processability are significantly improved without sacrificing quantitative performance during molding, and the molded products obtained are also good. The present invention was completed based on this discovery.
