Abstract : In the patent application, benzofuroisoquinoline ladder polymers are prepared by the condensation of 2,3,7,8-tetraaminobenzofuran with an aromatic tetracarboxylic acid or a dianhydride thereof. The polymers possess a high degree of thermal stability, a property which renders them particularly suitable for use in high temperature applications such as in the fabrication of plastic composites, fibrous materials and protective coatings.
