Abstract
A filtration media is disclosed comprising a hydrophobic monomer grafted onto a support, the hydrophobic monomer having the structure:CH═CRC(O)NHC(RR)(C(RR))C(O)XRwherein n is an integer of 0 or 1; Ris independently selected from at least one of: a hydrogen atom, alkyls, aryls, and alkylaryls, wherein the alkyls, aryls, and alkylaryls have a total of 10 carbon atoms or less; Ris a hydrophobic group selected from at least one of: alkyls, aryls, alkylaryls and ethers, wherein the alkyls, aryls, alkylaryls and ethers have a total number of carbon atoms ranging from 4 to 30; Ris H or CH; X is O or NH. In some embodiments the hydrophobic monomer is derived from an amine or an alcohol (HXR) that has a hydrophilicity index of 25 or less. Such media may be used in applications such as hydrophobic interaction chromatography.
