Scientific Research Applications

• Polyimide Synthesis: This compound has been used in the synthesis of polyimides. For instance, Tjugito and Feld (1989) synthesized polyimides using this compound with 1,2-bis(4-aminophenoxy)propane, which resulted in a polyimide soluble in various solvents and with good thermal stability (Tjugito & Feld, 1989) .
• Gas Permeability of Polyimide Membranes: Matsui, Sato, and Nakagawa (1998) explored the effects of ultraviolet irradiation on the gas transport properties of polyimide membranes prepared from this compound. Their study indicated an increase in gas selectivity due to irradiation, particularly in H2/N2 and H2/CH4 separations (Matsui, Sato, & Nakagawa, 1998).
• Polymer-Ceramic Composite Membranes: Rezac and Koros (1992) used this compound in the preparation of polymer-ceramic composite membranes with high gas fluxes and separating abilities. These membranes showed excellent gas separating performance, comparable to that of dense isotropic films (Rezac & Koros, 1992).
• Polyimide Properties: Feld, Ramalingam, and Harris (1983) conducted a study on polyimides derived from this compound, highlighting their good solubility in chlorinated solvents, low glass transition temperatures, and excellent thermal stability (Feld, Ramalingam, & Harris, 1983).
• Diamine Monomer Structure Influence: Langsam and Burgoyne (1993) studied the influence of diamine monomer structure on the gas permeability of polyimides prepared from this compound. They found correlations between diamine monomer structure and polymer permeability (Langsam & Burgoyne, 1993).
