Inverse model systems to investigate metal-support interactions in Fischer-Tropsch catalysis
… with silanes (i.e. tetraethoxysilane, trimethyl chlorosilane, triphenyl ethoxysilane). It is postulated that the formation of Co-O-Si will alter the catalytic properties of the cobalt site to which silane is bonded and the adjacent ligand-free sites. The desire is to understand the effects of …

Synthesis, characterization and kinetic investigations of heterophase materials prepared using group transfer polymerization
… which is subsequently terminated with a chlorosilane derivative of allyl methacrylate. The macromonomer technique has been employed to synthesize poly(methyl— methacrylate)—g-poly(dimethylsiloxane) copolymers of controlled molecular weight and apparent narrow molecular weight distribution …

Synthesis of well-defined single and multiphase polymers using various living polymerization methods
… followed by termination with a functionalized chlorosilane derivative. The methacryloyloxy functionalized PMMA macromonomers were prepared using group transfer polymerization with a protected hydroxyl functional initiator. The molar masses of the macromonomers ranged from 1000 g/mol up to 20000 …

Analysis of Alcohol and Alkylphenol Polyethers via Packed Column Supercritical Fluid Chromatography
… agent was achieved with phenylated disilazane-chlorosilane mixtures forming phenylsilylethers detected at 215 nm. Use of an organic solvent-modified CO2 mobile phase afforded lower pressure and temperature conditions for oligomer separation. The use of polar embedded alkyl phases combined with …

Lithium-aluminium casting alloys and their associated metal-mould reactions
… a sufficiently high standard and that tri-methylchlorosilane was consistently the best performer. Tri-methyl chlorosilane has a simple functionalizing mechanism compared to other hydroxide protecting reagents and this factor is responsible for its superior inhibiting qualities. Comparative …

New block copolymers of Isobutylene by combination of cationic and anionic polymerizations
… was also used to prepare four-armed star PIB via chlorosilane coupling. Using the same method, new amphiphilic block copolymers, namely PIB-b-poly(N,N-dimethylacrylamide) and PIB-b-poly(ethylene oxide) were synthesized. The anionic polymerization of N,N-dimethylacrylamide (DMAAm) was carried out …

Poly(2-alkyl-2-oxazoline) containing multiphase systems
… by termination with a benzyl chloride containing chlorosilane reagent. Cationic ring-opening polymerization of 2-ethyl-2-oxazoline using these macroinitiators in combination with NaI generated a series of well defined block copolymers. Poly(butyl vinyl ether) and poly(methyl vinyl ether) oligomers …

High Growth Rate and High Purity Semi-Insulating Epitaxy Using Dichlorosilane For Power Devices
… (0001) 80 off-axis substrates. Novel precursor Dichlorosilane (SiH2Cl2) is used as Siprecursor, using the idea that the silicon droplets can be dissolved by the presence of species that bind stronger to silicon than silicon itself. X-ray rocking curves indicate that the epilayers were of high …
