Abstract

Abstract Translated from German Die Erfindung betrifft organophile Doppelringkieselsäurederivate mit käfigartigen Strukturen der allgemeinen Formel I Si y O 2,5 y (SiR¹R²R³) n (SiR¹R²Q) y - n (I) worin y = 6, 8 oder 10; n = null bis (y - 1); R¹, R², R³ = Phenyl, C₁₋₅-Alkyl; und Q = H, Oh, Hal, Halogenalkyl, Halogenphenyl, Ethyl­phenyl, primärer Alkanolrest, C₂₋₂₀-Alkyl, C₂₋₈-Alkenyl, Epoxy, Silylalkyl, Siloxanylalkyl, Phenylmethylsilylalkyl, Phenyl, Alkenyl- oder Amin-substituiertes Phenyl, Carbonsäurerest oder Carbonsäure­derivatrest bedeutet. Die neuen Verbindungen bilden Polymerisate. Sie können wegen ihrer Festigkeit und Temperatur- und Ätzbeständig­keit als Beschichtungsmittel aber auch als Absorptionsmittel einge­setzt werden. Es werden Herstellungsverfahren beschrieben. The invention relates to organophilic double ring silicic acid derivatives with cage-like structures of the general formula I. Si y O 2.5 y (SiR¹R²R³) n (SiR¹R²Q) y - n (I) where y = 6, 8 or 10; n = zero to (y - 1); R¹, R², R³ = phenyl, C₁₋₅ alkyl; and Q = H, Oh, Hal, haloalkyl, halophenyl, ethylphenyl, primary alkanol radical, C₂₋₂₀ alkyl, C₂₋₈ alkenyl, epoxy, silylalkyl, siloxanylalkyl, phenylmethylsilylalkyl, phenyl, alkenyl- or amine-substituted phenyl, carboxylic acid residue or Carboxylic acid derivative means. The new compounds form polymers. Because of their strength and temperature and etch resistance, they can be used as coating agents but also as absorbents. Manufacturing processes are described.
