Patent ID: 7875182

Claim:
A size-selective porous polymer comprising of a plurality of pores, wherein all of said pores of said polymer have diameters from greater than 100 Angstrom to about 300 Angstrom, said polymer being capable of sorbing protein molecules greater than 20,000 to less than 50,000 Daltons from blood and excluding the sorption of blood proteins greater than 50,000 Daltons, said polymer having an effective pore volume and a capacity pore volume, said effective pore volume is from at least 0.306 cc/g to 0.986 cc/g, said effective pore volume is from at least 21.97% to 98.16% of said polymer's capacity pore volume, said effective pores having diameters from greater than 100 Angstroms to about 250 Angstroms and said polymer having oversized pores with a diameter greater than 251 Angstroms.
