Chemistry, Characterization and Processing of IMC Curing Polymers

A variety of methods for a low-cost synthesis of the IMC curable monomer, 2,2'-bis(phenyl-ethynyl)-4,4',5,5'-tetraaminobiphenyl, were explored without success. A low-cost route was found for the preparation of the IMC curable monomer, 2,2'-bis(phenylethynl)-5,5'-diaminobiphe...

Zusammenfassung:A variety of methods for a low-cost synthesis of the IMC curable monomer, 2,2'-bis(phenyl-ethynyl)-4,4',5,5'-tetraaminobiphenyl, were explored without success. A low-cost route was found for the preparation of the IMC curable monomer, 2,2'-bis(phenylethynl)-5,5'-diaminobiphenyl. Numerous model compounds with potential IMC reactions were prepared and characterized by thermal analysis. Some high molecular weight isoimide polymers were synthesized for study of the thermal rearrangement of the isoimide group to an imide group as an IMC-type reaction. (Author)
