| Research Abstract |
A novel preparation scheme for size-exclusion polymer chain, capable of adsorbing low-molecular-mass targets while retarding proteins, was suggested. Phosphate ionic species were adsorbed to the resultant porous hollow-fiber membrane, whereas bovine serum albumin was not adsorbed to the membrane. The successive addition of the reactants in the modification of the epoxy group of the graft chain provided a size exclusion structure for the graft chain.
