Latest Patents

Chen's patent titled "Microporous Polybenzimidazole Particulates" describes novel microporous particles of PBI resin. These particles are characterized by reduced bulk density, a surface area of at least 10 m²/g, a porosity of at least about 10%, and an average pore diameter ranging from 50 to 500 Angstroms. The patent outlines a method for creating these particles through emulsification-precipitation or atomizing-non-solvent quenching techniques. Notably, these microporous PBI particles are particularly well-suited for use as substrates in chromatographic processes such as ion-exchange, separations, and purifications, as well as in catalysis and chemical reagents in polymer-supported reactions. Further, variations in acidity/basicity and functional groups can be achieved by treating the PBI resin with different organic and inorganic acids either during or after particle formation.
