Hydrophilic super-macroporous polymer microsphere and preparation method thereof

The invention relates to the field of polymer microsphere preparation, in particular to a hydrophilic super-macroporous polymer microsphere and a preparation method thereof. The microsphere is prepared by using self-made amphiphilic block macromonomer as a surfactant through a suspension polymerization process; since hydrophilic chain segments are spontaneously arranged on the outer surface, facing a water channel, of the microsphere in a water-absorbing swelling process, hydrophobic chain segments participate in polymerization reaction through double bonds to be combined to the interior of a microsphere framework, so that the preparation and surface hydrophilic modification of the super-macroporous polymer microsphere are realized by one step. The hydrophilic super-macroporous polymer microsphere prepared by the preparation method disclosed by the invention adopts crosslinked polystyrene as the microsphere framework, is high in mechanical strength, good in chemical stability, good in hydrophilicity and super-macroporous, the outer surface of the hydrophilic super-macroporous polymer microsphere is sugar-containing polymer or polyvinyl alcohol gel. The hydrophilic super-macroporous polymer microsphere has a wide application space in the fields of enzyme immobilization and rapid separation and purification of protein.
