では困難であった。Polybutylene terephthalate (hereinafter abbreviated as PBT) has excellent properties such as heat deformation resistance, chemical resistance, impact resistance, and dimensional stability, and is used in connectors, relays, and electrical/electronic circuits for automobiles and home appliances. They are used as components in switches and other devices, but as the functions required of these devices increase, their shapes are becoming more complex, and there is also a need to make parts thinner to reduce costs and weight. In order to meet these demands, it is necessary for PBT resin to have high fluidity, easy mold release, and stable heat resistance during injection molding, but it is difficult to obtain PBT resin that satisfies all of these conditions using conventional technology. It was difficult.
