| Hazard Information | Back Directory | [Description]
2-(4-Aminophenyl)-1H-benzimidazol-5-amine (APBIA) is a synthetic raw material for the preparation of sulfonated polyimides containing benzimidazole (SPIBIs). The synthesised SPIBIs with polyhedral oligomeric silsesquioxane glycidyl ethers (G-POSS) can be used to prepare a number of novel organic-inorganic hybrid proton exchange membranes (PEMs). The obtained membranes exhibited good crosslink density at all gel fractions above 75%. The mechanical properties, oxidative stability and hydrolytic stability of the crosslinked membranes were significantly improved compared with those of pure SPIBI membranes. | [Safety Profile]
Low toxicity by ingestion. Whenheated to decomposition it emits toxic vapors of NOx. |
