Benzothiophenedioxideisoquinoline ladder polymers are synthesized by the condensation of 2,3,7,8-tetraaminodibenzothiophenes-5,5-dioxide with an aromatic tetracarboxylic acid or dianhydride thereof. The highly fused, aromatic-heterocyclic polymers so prepared have a high degree of thermal stability, a property that renders them particularly useful for high temperature applications, such as for plastic composites, fibrous materials and protective coatings.
