Mixtures of bis(silylorganyl)polysulfanes and silylorganylthiocyanates, their preparation and use

摘要

Mixtures of bis(organosilyl)sulphanes (IA) and organosilyl thiocyanates (IB) of formula: (R<1>R<2>R<3>SiR<4>)xX (I) (Where: X = Sn; n = 2-20, especially 2-8 if x = 2; and X = SCN if x = 1 (thiocyanato-silane); (a) R<1>, R<2>, R<3> = 1-8 carbon (C) alkyl and/or alkoxy or (b) at least one of R<1>, R<2>, R<3> = alkoxy, the rest = H or monovalent aryl, especially phenyl, tolyl or benzyl; R<4> = divalent 1-8, especially 2-4 C alkylidene or -(CH2)y-Phe-(CH2)y-; Phe = phenylene; y = 1-4.) Also claimed is a method of producing the mixtures.
