Abstract:
A macroporous polymer comprising polymerized monomer units of:(a) 50 to 100 percent by weight of one or more polyvinylaromatic monomer, and (b) zero to 50 percent by weight of one or more monounsaturated vinylaromatic monomer; wherein the polymer has:(i) a total porosity of 0.7 to 2 cubic centimeter per gram; (ii) an operational mesoporosity of 0.7 to 1.9 cubic centimeter per gram; (iii) an average particle size diameter of 2 to 600 microns; (iv) a surface area of 200 to 1500 square meters per gram; (v) a flow resistance value from 700 to less than 1,800 at 10 bar pressure and from 1,500 to less than 7,000 at 60 bar pressure; and (vi) a total insulin capacity of 75 to 150 grams insulin/liter of polymer and a dynamic insulin capacity of 60 to 150 grams insulin/liter of polymer.
