1. A blowing agent composition (a) which may be used to form elastomeric silicone foams consisting essentially of an aqueous emulsion containing organopolysiloxanes (1), emulsifiers (2), water (3) and thickener
30° off a normal to the rhodium atom towards the CH2SiMe3 groups with a Li … Rh distance of ca. 2.6 Å. Solution NMR spectroscopy as a function of temperature and solvent on these and the related iridates, (cod)Ir(CH2SiMe3)2Li(tmed) and (cod)Ir(R)2Li where R is Me or ...
R2is a hydrogen or a substituted or unsubstituted, linear or branched C1-C30hydrocarbon-based radical, preferably a hydrogen atom or an alkyl radical having at most 4 carbon atoms; R3represents a substituted or unsubstituted, linear, cyclic or branched C1-C30hydrocarbon-based radical, a substitut...
