Monomers, oligomers, and polymers of biscyclobutarenes bridged by at least one benzoxazole, benzothiazole or benzimidazole linkage |
| abstract |
A biscyclobutarene monomer is prepared comprising two parts of cyclobutarene bridged by a divalent radical having at least one benzoxazole, benzothiazole or benzimidazole bond. A reactive biscyclobutarene oligomer is also prepared by reacting a cyclobutarene carboxylic acid, a diaminodihydroxyarene, diaminodithiolarene or tetraaminoarene and either an aromatic diacid or an aromatic diacid chloride. The reactive monomers and oligomers can be polymerized to form polymers with remarkable thermo-oxidative stability at elevated temperatures for an extended period of time. |
