| introduction | 1, 3-bis (4'-aminophenoxy) benzene is a diamine monomer containing two ether bonds and three benzene rings, and the meta-substitution and chain structure of the ether bonds reduce the rigidity and flexibility of the molecular chain. This monomer is not only an important raw material for preparing homopolymerized or copolymerized PI, but also can be used for toughening modification of bismaleimide (BMI). |
