Abstract
Novel 2-(beta-maltooligooxy)-ethyl (meth) acrylate monomers are successfully synthesized by CGTase from Bacillus macerans catalyzed coupling of 2-(beta-glucosyloxy)-ethyl acrylate and methacrylate with a-cyclodextrin or starch. HPLC-UV analysis shows that the CGTase catalyzed reaction yields 2-(beta-maltooligooxy)-ethyl acrylates with 1 to 15 glucopyranosyl units. H-1 NMR spectroscopy reveals that the beta-linkage in the acceptor molecule is preserved during the CGTase catalyzed coupling reaction, whereas the newly introduced glucose units are attached by alpha-(1,4)-glycosidic linkages. The synthesized 2-(beta-maltooligooxy)-ethyl acrylate monomers are successfully polymerized by aqueous free radical polymerization to yield the comb-shaped glycopolymer poly(2-(beta-maltooligooxy)-ethyl acrylate).
