Preliminary chemical supply chain analysis. The production of legacy polyimide uses an aromatic dianhydride and an aromatic di-amines as the monomers, such as pyromellitic dianhydrides and 4,4'oxydianiline. Various anhydride and amines have been used in polyimides to adjust the polymer material properties. The poly(imide ester) networks access the same library of dianhydrides by converting them into diallyl monomers with a bis-imide core. It is worth noting that we have demonstrated the diallyl monomer synthesis, without process optimization, achieved >70% yield by using stoichiometric allyl amine reagents and no catalyst. To understand the chemical supply chain of our developed photopolymer at commercial scale, we sought to focus on the comparison to the legacy polyimides.
