Product Description:
3,3,4,4 - diphenylsulfonetetracarboxylic dianhydride usually exists as a solid, often in a white to light - yellow color. Structurally, it has a sulfone - linked diphenyl backbone with four carboxylic anhydride groups. It has low solubility in water but shows solubility in some organic solvents like N - methyl - 2 - pyrrolidone. This compound is relatively stable under normal conditions but can react with water or alcohols. It serves as a crucial monomer in the synthesis of high - performance polymers, especially polyimides, imparting excellent thermal stability, mechanical strength, and chemical resistance to the resulting polymers.

Application: 

3,3,4,4 - diphenylsulfonetetracarboxylic dianhydride is mainly used in synthesizing high - performance polyimides, which exhibit outstanding thermal stability, mechanical strength, and chemical resistance. These polyimides find applications in aerospace components, electronic packaging materials, and high - temperature - resistant coatings. It can also be applied in the preparation of special - purpose engineering plastics, enhancing their overall performance for use in harsh environments.
