METHOD FOR QUANTITATIVE ANALYSIS OF MONOMERS IN POLYIMIDE FILM

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.
