We present the synthesis and characterization of amphiphilic AB diblock copolymers containing a crosslinkable segment. Both sequential anionic, as well as nitroxide mediated polymerization (NMP) techniques were used to obtain well defined block copolymers containing either poly(styrene-co-isoprene) (P(S-co-I)) or poly(furfuryl glycidyl ether) (PFGE)1 as hydrophobic block. As hydrophilic segments either poly(ethylene oxide) (PEO) or stimuli responsive poly(N,N-dimethylaminoethyl methacrylate) (PDMAEMA) has been employed (Figure 1). The materials were characterized by size exclusion chromatography and NMR-spectroscopy. Crosslinking of the hydrophobic block in different (nanostructured) environments was achieved by UV-induced radical polymerization (P(S-co-I)) or Diels-Alder reactions using a bisfunctional maleimide (PFGE). We demonstrate the application of such block copolymers for the formation of nanoporous membranes or the preparation of organic/inorganic hybrid nanoparticles.1. Barthel, M.
