POLYETHER SULFONE FILM AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a thick polyether sulfone (PES) film having surface smoothness and a low retardation value by laminating the PES films manufactured by a melt extrusion method. SOLUTION: The polyether sulfone film is manufactured by laminating a plurality of the polyether sulfone films through a saturated plyester resin.
