Polysiloxanes containing polyhedral oligomeric silsesquioxane groups in the side chains; synthesis and propertie
(2296-2304)  Polymer 51 #11 (2010)
Ryu, Kim and Lee prepared linear polysiloxanes having different amounts of polyhedral oligomeric silsequioxane (POSS) side groups from the hydrosilylation reaction of poly(ethylhydrosiloxane) with different amount of POSS and 1-octene using platinum(0)-divinyl tetramethyldisiloxane as a catayst.  The linear polysiloxanes with POSS side groups are soluble in various organic solvents. When the content of POSS-containing monomeric unit is larger than 10 mol%, free standing films can be prepared from a routine solution casting method, although this polysiloxane is not cross-linked.  (RDC 12/22/2010)
