Method for quantitative analysis of monomers in polyimide film |
| 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. |
