Hydrophilic Modification of Polysulfone Membrane Material by Coupling Grafting of Polyethylene Glycol Monomethylether
偶合接枝聚乙二醇单甲醚实现聚砜膜材亲水性改性

In the presence of acid-acceptor Na2CO3,the nucleophilic substitution between chloromethylated polysulfone(CMPSF) and polyethylene glycol monomethyl ether(PEGME) was conducted,and polyethylene glycol(PEG) was coupling-grafted onto the side chains of polysulfone(PSF),so that the graft copolymer PSF-g-PEG was prepared and the hydrophilic modification of polysulfone membrane material realized.The chemical structure of PSF-g-PEG was characterized.The effects of main factors on the coupling graft reaction were e...
