Title:
REVERSE PHASE SEPARATING MEMBRANE
Document Type and Number:
Japanese Patent JP3499978
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To manufacture a superior reverse phase separating membrane which can select various functional groups in compliance with the nature of a material to be dealt with by graft polymerizing a polymerizable monomer provided with a hydrophobic functional group with a porous polymer material membrane.
SOLUTION: A polymerizable monomer with a hydrophobic functional group such as octadecyl (meth)acrylate or tridecyl (meth)acrylate is graft polymerized with a porous polymer material membrane such as olefin or polyamide. Then, the hydrophobic functional group is fixed on a porous polymer membrane material. A polymer membrane thus formed is utilized as a reverse phase separating membrane for reverse phase column chromatography. A wide range of fixing amount of the hydrophobic functional group can be controlled by the membrane, and various functional groups can be selected in compliance with the nature of a material to be dealt with. As hydroxyl group is not contained in the membrane, separation can be carried out simply by the mutual action of the hydrophobic groups and a separation pattern of good reproducibility and without tailings can be provided.
