ENDLESS BELT |
摘要 |
Disclosed herein is a method of manufacturing an endless belt, including the steps of: reacting a diamine monomer with a dianhydride monomer in a reactor filled with a conductive filler-dispersed liquid to obtain a reaction product, aging the reaction product and then discharging the aged reaction product from the reactor to prepare a semiconductive polyamic acid solution having a molecular weight distribution (Mw/Mn) of 1.3˜3.0 and a weight average molecular weight (Mw) of 30,000˜300,000; and applying the semiconductive polyamic acid solution to a seamless mold and completing an imidization reaction to obtain a polyimide film. |
