“…For IPTS,SM-IATE and DPPETES, mono-, di-, tri-substituted siloxane bonds are designated as T 1 , T 2 , T 3 . The chemical shifts of T 2 and T 3 are À56 and À65 ppm, respectively, and conform to the literature values [16,17]. These data suggest the complete hydrolysis and condensation.…”

Comb-like polysiloxanes with polyhedral oligomeric silsesquioxane (POSS) and oligo(ethylene oxide) groups (EO) in the side chains were prepared through the hydrosilylation reaction of poly(ethylhydrosiloxane) (PEHS) with 1-allyl-3,5,7,9,11,13,15-heptacyclopentylpentacyclo-[9.5.1.1 3,9 .1 5,15 .1 7,13 ] octasiloxane (allyl-CyPOSS) and allyl-functionalized oligo(ethylene glycol) monomethyl ethers. The physical and chemical properties of these polysiloxanes were studied systematically by changing the content of bulky POSS groups and hydrophilic flexible oligo(ethylene oxide) groups with different lengths. For example, the glass transition temperature of the polymer increased with increasing content of POSS side groups, whereas the melting temperature and heat of fusion of the oligo(ethylene oxide) side group decreases. Furthermore, the glass transition temperature and melting temperature increase when the length of the EO group was increased, whereas the decomposition temperature decreased.

“…This behaviour is characteristic of the thermal stability of POSS which stems from its silicon-oxygen structure. A proposed mechanism of thermal reinforcement is that POSS molecules restrict polymer chain motions, due to polymer-filler interactions or by the large inertia exhibited by segments of polymer containing POSS [23,24]. The compatibilising 'R' groups on the POSS encourage this interfacial interaction, allowing thermal reinforcement to be achieved.…”

Abstract. Nanocomposites consisting of poly(styrene-b-butadiene-b-styrene) (SBS) and polyhedral oligomeric silsesquioxanes (POSS) were prepared using a solvent dispersion method. POSS molecules were functionalised with two dichlorotriazine reactive dyes (CI Reactive Blue 4, CI Reactive Red 2) prior to compounding. Infrared spectroscopy confirmed functionalisation. Scanning electron microscopy revealed an increase in filler aggregation with concentration, with preferential phase selectivity. Ultraviolet spectroscopy and colourimetry confirmed colour uniformity and suggested that colour intensity could be controlled. Functionalised POSS improved thermal stability by imparting restrictions on SBS chain motions. Tensile stress-strain analysis revealed an increase in modulus with filler concentration, while creep deformation decreased and permanent strain increased with POSS content. Storage modulus, loss modulus and glass transition temperature increased with filler content due to effective SBS-POSS interaction. Nanocomposite properties were influenced by the phase the filler was dispersed throughout and the structure of the dye chromophore.
