Preparation of Uniform Hypercrosslinked Microspheres with Large Specific Surface Area

摘要

The membrane emulsification-suspension polymerization (MESP) method was used to synthesize hypercrosslinked microspheres with a narrow size distribution. The resulting polymers possessed large specific surface area (over 1300 m /g) and their particle size was controllable. The particles were more hydrophilic when using nitrobenzene as solvent instead of 1,2-dichloroethane in the postcrosslinking process.
