Abstract
Alkyl-silicates and alkyl-silicate-containing organosilicon compounds. The alkyl-silicate-containing organosilicon compound includes at least 90% by weight, preferably at least 95% by weight, of alkyl silicates of average formula (I)[SiO][(RO)SiO][(RO)SiO]'[(RO)SiO][(RO)(RO)SiO]′[(RO)SiO]″[(RO)SiO][(RO)(RO)SiO]′[(RO)(RO)SiO]″[(RO)SiO]d′″ (I).Where the radicals Rare each independently selected from radicals that meet at least one of the following conditions: (a) where Ris a substituted or unsubstituted, C-Chydrocarbon radical that is branched at the α-carbon atom, (b) where Ris a substituted or unsubstituted, C-Chydrocarbon radical that is doubly branched at the β-carbon atom, and/or (c) where Ris an unsubstituted or alkyl-substituted cyclopentyl, cyclohexyl or cycloheptyl radical having a total of not more than 9 carbon atoms. Where the radicals Rare each independently selected from (i) hydrogen, (ii) methyl radical, and (iii) ethyl radical.
