A series of the dumbbell shape nanocomposite materials of polydimethylsiloxanes (PDMS) and polyhedral oligomeric silsesquioxanes (POSS) was synthesised through hydrosilylation reaction of allyl-POSS and hydride-terminated PDMS. The chemical structures of the dumbbell shaped materials, so called POSS-PDMS-POSS triblocks, were characterised by 1H NMR and FT-IR spectroscopy. The impact of POSS on the molecular mobility of the PDMS middle chain was observed by using 1H spin-spin (T2) relaxation NMR. In contrast to the linear melts the triblocks showed an increase in mobility with increasing molecular weight over the range studied due to the constraints imposed by the tethered nanoparticles. Incorporation of the triblocks in homopolymer melts was compared to conventional nanocomposites.
