Patent ID: 10807069

Abstract:
A filtration media is disclosed comprising a hydrophobic monomer grafted onto a support, the hydrophobic monomer having the structure: CH2═CR4C(O)NHC(R1R1)(C(R1R1))nC(O)XR3  wherein n is an integer of 0 or 1; R1 is 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; R3 is 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; R4 is H or CH3; X is O or NH. In some embodiments the hydrophobic monomer is derived from an amine or an alcohol (HXR3) that has a hydrophilicity index of 25 or less. Such media may be used in applications such as hydrophobic interaction chromatography.
