MOLECULAR SIEVING PARTICLE AND PREPARATION THEREOF

摘要

A novel molecular sieving particle containing adsorbent powders dispersed in matrix of micro-porous polymer gels is prepared by dispersing adsorbent powders into a polymeric material solution dissolved in a solvent, then emulsifying the thus prepared dispersion into a vehicle having a boiling point higher than that of the solvent and finally removing the solvent by evaporation. This molecular sieving particle has excellent molecular sieving effect as well as excellent adsorption capacity, and applicable in various applications.
