Abstract: A method for preparing a polyetherimide/polyester blend chip includes providing a composition. The composition includes a polyetherimide powder and a polyester powder. The polyetherimide powder has a variable diameter in a range of 10 ?m to 600 ?m. The polyester powder has a variable diameter in a range of 10 ?m to 600 ?m and a limiting viscosity in a range of 0.85 dl/g to 1.10 dl/g. Then, performing a powder dispersion treatment on the composition. The composition undergoes melt compounding after performing the powder dispersion treatment. The composition is next pelletizing melt compounding.

Abstract: A composition for preparing a polyetherimide/polyester blend chip includes a polyetherimide powder and a polyester powder, in which the polyetherimide powder has an amount greater than 70 wt % and less than or equal to 90 wt % based on a total weight of the polyetherimide powder and the polyester powder, and the polyester powder has an amount greater than or equal to 10 wt % and less than 30 wt % based on the total weight of the polyetherimide powder and the polyester powder. The polyetherimide/polyester blend chip made of the composition is amorphous.
