Dicarboxyphenoxy

In organic chemistry, a dicarboxylic acid is an organic compound containing two carboxyl groups (−COOH). The general molecular formula for dicarboxylic acids can be written as HO2C−R−CO2H, where R can be aliphatic or aromatic. In general, dicarboxylic acids show similar chemical behavior and reactivity to monocarboxylic acids. Dicarboxylic acids are used in the preparation of copolymers such as polyamides and polyesters. … WebJun 7, 2024 · The objective of this study was to investigate the effects of diamines with ether group or/and trifluoromethyl (-CF 3) group on the optical properties of polyimides.
