Anti-adhesive and low-fouling properties have a particular interest in some biomedical applications to avoid non-specific cell attachments. In this work, copolymers of carboxymethyl dextran (CMD) and poly(butyl methacrylate) (PBMA) are successfully obtained by free radical copolymerization. The effects of CMD substitution degrees and CMD/BMA ratio on the copolymerization yields are investigated. Copolymers compositions are determined by carbon solid state nuclear magnetic resonance(13C-NMR), Attenuated total reflectance Fourier transform infrared spectra (ATR-FTIR) and by high performance size exclusion chromatography (HPSEC). Results indicate that copolymers are composed of CMD and a majority of PBMA, and PBMA chains are 10-fold longer than CMD ones. Solubility is investigated, and fil... view more»
