Effect of ferrocene on the synthesis of graft copolymers of vinylpolysiloxane and styrene

Block-copolymeric maltodextrin-based amphiphilic glycosilicones as surface-active systems

“…a,o-Hexavinylpolydimethylsiloxane (M w = 80 000, M n = 33 800) was synthesized by the known recipe. 21 . The NMR spectra were calibrated with the help of 2 H NMR signals of the solvent as an internal secondary standard and converted to the tetramethylsilane (TMS) scale using the unified X scale, according to the IUPAC recommendations.…”

Fabrication and electrical study of large area free-standing membrane with embedded GaP NWs for flexible devices

“…PDMS-St was synthesized in accordance with the routine reported in [40]. Freshly distilled styrene (Aldrich), α,ωbis(trivinylsiloxy)PDMS (1.3 mol% vinyl groups, the weightaverage molecular weight M w = 65 500, the number-average molecular weight M n = 36 000, the polydispersity coefficient Ð = 1.8, the synthesis was performed based on [40]), azobisisobutyronitrile (AIBN, 98%, Aldrich, recrystallized from ethanol twice before usage) and ethanol (96.5%) were loaded into a three-necked flask equipped with a reflux condenser, stirrer, and heater. The styrene loading was 60 wt% of α,ωbis(trivinylsiloxy)PDMS, and the AIBN loading was 0.8 wt% [40].…”

GPC was carried out on a Shimadzu LC-20AD chromatograph equipped with a refractometric detector and a TSKgel G5000HHR 7.8 mm × 30 cm column (Tosoh Bioscience).…”

“…The calculation of molecular weights was carried out using polystyrene standards. PDMS-St was fully characterized by NMR spectroscopy [40].…”
