“…THF (tetrahydrofurane) was purchased from Avantor Performance Materials Poland S.A. and used as received. Poly(dimethyl-co-(methyl{3-(2,2,3,3,4,4,5,5-octafluoropentyloxy)propyl})-co-(methyl,{3-glycidoxypropyl}) siloxane was synthesized according to methodology given by the authors elsewhere [30][31][32].…”

Novel gelatin-siloxane hybrid monoliths for heavy metal removal were prepared in the chemical reaction of gelatin with organomodified silicone containing epoxy group. Obtained porous hybrid materials were applied for adsorption of Cu(II), Cd(II) and Pb(II) from aqueous solutions. In this paper, the influence of siloxane amount used for the modification of gelatin on adsorbent stability and heavy metal removal was examined. The effect of pH values of the immersion liquid, as well as the contact time, was studied. Morphology, compressive strength and water absorption of hybrid monoliths were investigated. Desorption tests were also performed. The results showed that the higher the amount of the siloxane, the better stability of the hybrid monoliths in aqueous solutions. The highest values of adsorption capacity were observed for Pb(II) ions. The experimental maximum adsorption capacity determined for hybrid monoliths was 3.75 mg/g for Pb(II), 1.76 mg/g for Cu(II) and 1.5 mg/g for Cd(II). The desorption of metal ions for hybrid monoliths stable in aqueous solutions reached 70%.

“…[46] Recently, Marciniec and co-workers have reported that dimeric rhodium siloxide [(cod)Rh(μ-OSiMe 3 )] 2 (41) is a much more effective catalyst in the hydrosilylation of aliphatic and aromatic olefins, vinylsilanes, and allyl alkyl ethers than the respective rhodium complex [(cod)Rh(μ-Cl)] 2 and the commercially available Pt-Karsted catalyst most frequently used in hydrosilylation chemistry. [47] The hydrosilylation of olefins with [(cod)Rh(μ-OSiMe 3 )] 2 as the precatalyst proceeds by initial oxidative addition of the HSiR 3 followed by subsequent elimination of R 3 SiOSiMe 3 to generate the square-planar 16e -alkene complex 42 as the actual catalytically active species (Scheme 11).…”

New phenylene-silylene-ethylene polymers have been successfully synthesized using platinum-divinylsiloxane or rhodium and iridium siloxide complex-catalysed polyhydrosilylation of divinylsubstituted carbosilanes with dihydrocarbosilanes or intermolecular hydrosilylation of new hydrovinylcarbosilane. Polycarbosilanes have been obtained with high molecular weights. They seem to be potential parent substances for future applications as preceramic and membrane materials.
