Abstract : Thermally stable dioxo and dithio-benzisoquinoline polymers are synthesized by the polycondensation of oxyarylene and thioarylene bis-naphthalic acid dianhydrides and aromatic diamino compounds. The compositions are particularly useful in high temperature applications such as in the fabrication of plastics, composites, fibrous materials, protective coatings and films.
