METHOD OF MANUFACTURING COMPOSITION FOR PREPARING POLYETHERIMIDE/POLYESTER BLEND CHIP

摘要

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 μm to 600 μm. 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. 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.
