Method of manufacturing composition for preparing polyetherimide/polyester blend chip

A method for preparing a polyetherimide/polyester blend chip, comprising:

• providing a composition for preparing a polyetherimide/polyester blend chip, the composition comprising:
• a polyetherimide powder, wherein the polyetherimide powder has a variable diameter in a range of 10 μm to 600 μm;
• and
• a polyester powder, wherein the polyester powder has a variable diameter in a range of 10 μm to 600 μm and a limiting viscosity in a range of 0.85 dl/g to 1.10 dl/g, 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;
• performing a powder dispersion treatment on the composition;
• melt compounding the composition after performing the powder dispersion treatment;
• and
• pelletizing the composition after melt compounding the composition.
