AbstractA simple one-step method for the chloromethylation of polyethersulfone (PES) under mild conditions provided surface benzyl chloride groups as the active initiators for the surface-initiated atom-transfer radical polymerization (ATRP) to tailor the functionality of the PES membrane. Functional hydrophilic polymer brushes of poly(ethylene glycol)monomethacrylate (PEGMA) and sodium 4- styrenesulfonate (NaStS), as well as their block copolymer brushes, were prepared via surface initiated ATRP from the chloromethylated PES surfaces. X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM) were used to characterize the surface-modified membranes. The PEGMA-grafted PES membranes showed great protein resistance to protein adsorption compared to the pristine PES surface.

Novozyme 435

Enzymatic polycondensation of benzyl-2,2-bis(methylol) propionate and sebacic acid has been performed using lipase Novozyme-435 as the catalyst, subsequently enzymatic ring-opening polymerization was reacted by adding ε-caprolactone as the monomer in the same system. Then atom transfer radical polymerization (ATRP) from the macroinitiator combining α-bromoester of styrene was catalyzed by CuCl/2,2’-Dipyridyl to obtain the block copolymer successfully. The polymers obtained in different conditions were analyzed by 1HNMR and GPC.
