The invention provides a preparation method of super-macroporous polymeric microspheres and a product thereof. The method is characterized in that adding high content of surfactant into an oil phase containing a monomer and dispersing the oil phase containing the monomer and the surfactant into an aqueous phase. Super-macroporous microspheres are obtained by means of suspension polymerization. In the interior of the microspheres, 10-60% of the pores are distributed in a range of 500-900 nm. The microspheres have a particle diameter of 1-200 μm and a porosity of 30%-90%. The product is suitable for being used as a stationary phase matrix in liquid chromatography, a carrier for high performance catalysts and a high performance adsorbent, and especially, being used as a separation medium for separating biomacromolecules.
A method for preparing super-macroporous polymeric microspheres, which in the interior thereof comprising micropores with a pore diameter of 10-200 nm and super macropores with a pore diameter of 500-900 nm, wherein the super macropores comprise 10-60% of the inner pore volume of the microsphere, said method comprising:
