Abstract: Triphenylgermylsilane (Ph3Ge—SiH3) is useful for the production of germanium-silicon layers (Ge—Si) or as transfer agent of silane groups (SiH3). Further, a method describes the production of triphenylgermylsilane (Ph3Ge—SiH3) by reducing trichlorosilyl-triphenylgermane (Ph3Ge—SiCl3) with a hydride in solution, and another method describes the production of trichlorosilytrichlorogermane (Cl3Ge—SiCl3) by reacting trichlorosilyltriphenyigermane (Ph3Ge—SiCl3) with hydrogen chloride (HCl) in the presence of AlCl3 in solution. In addition, trichlorosilyltrichlorogermane is also used for the production of germanium-silicon layers (Ge—Si).
Abstract: Polyalkyl(meth)acrylate based comb polymers with weight-average molecular weights of 700,000 g/mol or greater and number-average molecular weights of 130,000 g/mol or greater can be used to improve the high temperature-high shear performance of lubricant compositions, especially of engine oil (EO) compositions. These polymers can be obtained in a reaction mixture comprising monomers, a dilution oil, and an initiator. The resulting lubricant compositions can have improved kinematic viscosity and high temperature high shear performance.
