However, when used as an injection molded product in plastic applications, polyethylene terephthalate has many disadvantages in molding due to its special crystallization behavior. That is,
Polyethylene terephthalate is originally formed as a crystalline 1R aggregate, but because it has a high secondary transition point, it is especially difficult to mold with general-purpose thermoplastic resin molding machines! 7 usually laughed at 10
When molding is performed at a skeleton temperature of 0° C. or lower, the shape stability of the molded product at temperatures above the secondary transition point becomes significantly poor. Not only does the residence time in the mold take a long time, resulting in poor mold releasability, but it also has drawbacks such as the occurrence of Vζ avatar-like or flowing patterns on the surface of the molded product. have. As the most effective technique to eliminate all of the drawbacks of cit et al., the crystallization initiation temperature of riboethylene terephthalate is shifted to the lower temperature side, and the crystallization rate is monitored. 8 parts by weight of a butylene terephthalate polyester, 5 to 5 ozy parts of a butylene terephthalate polyester, and 0.2 to 10 parts by weight of an epoxy compound having a polyoxyalkylene chain association.

[Problems to be solved by EiA] When the above-mentioned conventional polyester composition was actually injection molded, strength problems occurred due to the shape of the molded product and the number of gates (90,000). When injection molded products are used as industrial parts, it is difficult to assemble them by ultrasonic welding.
In many cases, the strength of this welded portion may be so weak that it becomes a problem. These problems cannot be improved by using fibrous reinforcement materials.

A compound tip was obtained.This compound tip gold was heated at 130°C.
After drying under reduced pressure for 17 hours, the test piece was completely molded, and the anisotropy of weld strength, ultrasonic bath N strength, and maximum bending strain was evaluated. Each result is shown in Table 1.
