PROBLEM TO BE SOLVED: To provide an amorphous polyester chip capable of obtaining a molded article having a uniform polymer composition and a method for producing the same. In particular, the present invention provides an amorphous polyester chip and a method for producing the same, which can improve the processing operability at the time of molding and can efficiently produce a molded article having a uniform polymer composition. [Solution] The amorphous polyester chip of the present invention is characterized in that the moisture content is 300 ppm or less and the content of fine particles is 500 ppm or less. Amorphous polyester chips of the present invention, after cooling the amorphous polyester obtained by melt polymerization, the chips obtained by cutting, thrown into the treatment tank of the fluidized-bed dryer, when passing Drying by passing dry gas through, or drying in a dryer drying device under vacuum or by passing a small amount of dry gas under vacuum, and then transferring to a fine particle removing device without contacting with outside air. To remove fine particles. [Selection diagram] None |
