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. … Web第36卷第1期. 2008年1月化 学 工 程. chemicalengineering(china)vo.l36no.1. jan.2008. 偶联剂对聚酰亚胺/sio2杂化膜性能的影响
