A method of blending polyimide oligomers with active carboxyl and hydroxyl functional groups with two types of epoxy resins (difunctional and tetrafunctional)has been researched with an objective of studying their compatibility and the effect of the resulting resin matrices on the performance properties. The project is divided into the following parts: (1) synthesis and characterization of 4,4-diamino-4-hydroxytriphenylmethane (DAHTM) monomer using aniline hydrochlorate as the catalyst; (2) synthesis and characterization of carboxylic imide 4,4-diamino-4-hydroxytriphenylmethane (CIDAHTM) and...
