Novel polymer nanocomposites based on polystyrene and Ti-functionalized polyhedral silsesquioxanes
(848–853)Polymers for Advanced Technologies 21 #12 (2010)
Monticelli  et al of Italy prepared Ti-based polyhedral silsesquioxanes (Ti-POSSs) have been prepared and dispersed in polystyrene (PS), by in situ polymerization.  PS nanocomposites of the samples based on heptaisobutyl-Ti-POSS (HEI-Ti-POSS) are formed, where HEI-Ti-POSS cages are directly linked to the macromolecules via Ti-C bonds. The presence of HEI-Ti-POSS enhances the thermo-oxidative stability of PS-based nanocomposites and does not significantly affect the polymer molecular mass.  (RDC 2/4/2011)

Synthesis of core-shell particles by batch emulsion polymerization of styrene and octavinyl polyhedral oligomeric silsesquioxane
(13-17) Journal of Polymer Research 18  #1 (2011)
Wang et al prepared new composite octavinyl POSS-PS was prepared by batch emulsion polymerization initiated by potassium persulfate.  The incorporation of POSS can apparently improve the thermal stability of PS.  (RDC 12/9/2010)
