✦ Synopsis

The cationic polymerization of 2-vinylfuran initiated with triphenylmethyl chloride in conjunction with silica nanoparticles in suspension yields poly(2-vinylfuran)/silica hybrid particles and a soluble fraction of oligo(2-vinylfuran). 2-Vinylfuran cationically is polymerized via both the vinyl double bond and the 5-position of the furan ring. The formation of the resulting crosslinked poly(2-vinylfuran) network structure on the surface of the silica particles is examined by means of different kinds of NMR spectroscopy and an assignment of the signals is given.
