Green Polymer Chemistry: Telechelic Poly(Ethylene Glycol)S via Enzymatic Catalysis

This article reports our discovery that poly(ethylene glycol) (PEG) can quantitatively be functionalized by transesterification using Candida antarctica lipase B (Novozyme 435) as the catalyst. α-ω telechelic PEG-methacrylates and PEG-acetates were successfully prepared using commercially available...

Description
Summary:This article reports our discovery that poly(ethylene glycol) (PEG) can quantitatively be functionalized by transesterification using Candida antarctica lipase B (Novozyme 435) as the catalyst. α-ω telechelic PEG-methacrylates and PEG-acetates were successfully prepared using commercially available PEGs with both narrow and broad molecular weight distribution. 1H and 13C NMR together with MALDI-TOF mass spectroscopy verified the expected structures. © 2008 Wiley Periodicals, Inc.
