ORGANOSILICA MATERIALS AND USES THEREOF

Methods of preparing organosilica materials, which are a polymer comprising of at least one independent cyclic polyurea monomer of Formula wherein each R1 is a Z1OZ2Z3SiZ4 group, wherein each Z1 represents a hydrogen atom, a C1-C4 alkyl group, or a bond to a silicon atom of another monomer unit; eac...

Zusammenfassung:Methods of preparing organosilica materials, which are a polymer comprising of at least one independent cyclic polyurea monomer of Formula wherein each R1 is a Z1OZ2Z3SiZ4 group, wherein each Z1 represents a hydrogen atom, a C1-C4 alkyl group, or a bond to a silicon atom of another monomer unit; each Z2 and Z3 independently represent a hydroxyl group, a C1-C4 alkyl group, a C1-C4 alkoxy group or an oxygen atom bonded to a silicon atom of another monomer unit; and each Z4 represents a C1-C8 alkylene group bonded to a nitrogen atom of the cyclic polyurea are provided herein. Methods of preparing and processes of using the organosilica materials, e.g., for gas separation, color removal, etc., are also provided herein.
