CPI is usually synthesized from dianhydride and diamine monomers

As a result of distinctive polymerization processes. Having said that, the high Price and artificial issues for useful dianhydrides have greatly confined the development and commercialization of CPI movies (Matsumoto, 2000). Reaction problems for example ozone, photoirradiation and large-stress oxidation with nitric acid tend to be Utilized in the synthesis of dianhydrides. Moreover, the overall … Read more
