METHOD FOR SYNTHESIZING BISIMIDE MONOMER AND POLYETHERIMIDE SYNTHESIS METHOD THEREBY

摘要

The present invention relates to a method for synthesizing a bisimide monomer, comprising the following steps: adding phthalic anhydride and diamine in a polar aprotic solvent; and chemically setting phthalic anhydride and diamine. The present invention further relates to a polyetherimide synthesis method, comprising a step of obtaining polyetherimide by continuously conducting a reaction after loading anionic monomers into a reactor in which the chemical setting process is proceeded.;COPYRIGHT KIPO 2017
