Abstract
PURPOSE:To provide the title composition which hardly gives rise to hopper bridges when a compound is prepared, less soils a mold, and gives a molded product improved in mechanical strengths, by incorporating a specific silane coupling agent into a thermoplastic polyester. CONSTITUTION:The title composition contains 0.05-5pts.wt. silane coupling agent having one or more epoxy groups in the molecule (e.g., 2,3- epoxypropyltrimethoxysilane) per 100pts.wt., thermoplastic polyester (e.g., polyethylene terephthalate resin or polybutylene terephthalate resin). When the composition is employed, hopper bridges hardly occur when a compound is prepared, soiling of a mold hardly occurs in molding and the mechanical strengths of the obtained molded product are improved. In the case of the silane coupling agent which does not contain an epoxy group, soiling of a mold is hardly improved, while a compound which contains an epoxy group but does not acts as silane coupling agent may lower the flow stability during working sometimes unfavorably.
