    Abstract: Mixtures of linear and cyclic amino-functional siloxane oligomers containing: (i) 3-aminopropyl, N-(2-aminoethyl)-3-aminopropyl or N'-(2-aminoethyl)-N-(2-aminoethyl)-3-aminopropyl groups; (ii) optional alkoxy groups; and (iii) (cyclo)alkyl, alkenyl or aryl groups. Mixtures of chain-type and cyclic siloxane oligomers of formula (I) and (II): R = (i) groups of formula -(CH2)3-NH2, -(CH2)3-NHR', -(CH2)3-NH-(CH2)2-NH2 or -(CH2)3-NH-(CH2)2-NH-(CH2)2-NH2, with not more than one aminopropyl-functional group of this type attached to a silicon atom, (ii) methoxy, ethoxy, 2-methoxyethoxy and/or propoxy groups, with a silicon/alkoxy group mol ratio of at least 0.5 and optionally (iii) 1-18C alkyl, alkenyl, iso-alkyl or cycloalkyl, or 6-12C aryl; R' = linear, branched or cyclic 1-18C alkyl, or 6-12C aryl; m = more than 2 and less than 30; n = 3-30 An Independent claim is also included for a process for the production of these mixtures from mixtures of: (A) aminopropyl-functional trialkoxy- or methyldialkoxy-silanes; optionally (B) 1-18C alkyl-, alkenyl-, isoalkyl- or cycloalkyl-trialkoxysilanes and/or phenyl-trialkoxysilanes and/or corresponding methyldialkoxy silanes; and optionally (C) a tetra-alkoxysilane, by hydrolysis and condensation (in succession or as a mixture) at 10-95 degrees C with 0.6-1.2 mols water per 1 mol silicon and 0.1-5 times the weight of methanol or ethanol (based on alkoxysilanes), followed by distillation of alcohol at up to 120 degrees C under normal or reduced pressure.

    Abstract: Alcohol-based, fluoroalkyl-functional organosiloxane-containing compositions are obtained by hydrolysis of fluoroalkyl- organosilanes of formula R -Y-(CH2)2SiHx(R )y(OR)3-x-y (I), where R, R = linear, branched or cyclic 1-8C alkyl, or aryl; R = mono-, oligo- or per- fluorinated 1-9C alkyl or aryl; Y = CH2, O or S; x, y = 0, 1 or 2; and x+y = not more than 2. The reaction is carried out for 0.5-24 hours at 0-120 degrees C with good stirring in an alcoholic medium containing water together with a weak mono- or poly-basic acid and/or a weak base or an acid or basic salt, with a molar ratio of water:(I) = (2-500):1. Also claimed is the above process for the production of these compositions.

    Abstract: Stable composition of water-soluble organosiloxanes, obtained by reacting water-soluble amino-alkoxy-silane (A) with insoluble alkenyl-alkoxy-silane (B), then adding water and removing alcohol, using (A) and water in amounts such as to enable reaction of all alkoxy groups in (B) and adjusting to pH 2-6 with acid. A stable composition of water-soluble organosiloxanes obtained by (a) reacting a water-soluble, amino-functional alkoxysilane (A) with water-insoluble alkenyl-functional alkoxy-silane(s) (B), (b) adding water and (c) removing the alcohol formed. The amounts of amino-silane (A) and water used are such as to enable reaction of all the alkoxy groups in (B) and to give a composition from which essentially no alcohol is liberated by hydrolysis on dilution with water. This composition is adjusted to a pH of 2-6 by adding an optionally aqueous organic or inorganic acid during and/or after the reaction. An Independent claim is also included for a process as described above for the production of such compositions.

    Abstract: Process for treatment of discoloration of aminosilane comprises: (1) adding acid chloride in molar excess to discolored aminosilane; (2) neutralizing excess of acid chloride with a molar deficit of base to obtain a mixture containing salt of acid chloride and base; (3) separating off salt to leave treated aminosilane; and (4) irradiating treated aminosilane with UV-containing light.
