Title:
METHOD FOR QUANTITATIVE ANALYSIS OF MONOMERS IN POLYIMIDE FILM
Document Type and Number:
WIPO Patent Application WO/2019/098524
Kind Code:
A1
Abstract:
The present invention can provide an analysis method, wherein a measurement sample containing a diamine and an acid dianhydride can be obtained without a separate methyl derivatization process by pretreating a polyimide film as a poorly soluble polymer with DMAc after hydrolysis, and the content analysis of monomers contained in the polyimide film can be universally utilized by using such a pre-treatment method.
