(57) [PROBLEMS] To obtain a PBT pellet for molding in which the molding stability is remarkably improved without impairing the releasability of polybutylene terephthalate (hereinafter abbreviated as PBT). SOLUTION: A mixed ester consisting of a long-chain aliphatic monocarboxylic acid, a dicarboxylic acid and a polyol is blended with PBT, and the surface of the pellet is scratched, whereby B It is possible to obtain a molded product which is excellent in mold releasability of the molded product and is also excellent in molding stability during recycling without impairing the mechanical properties of PT. |
