    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: Prepn of 3-(pseudo)haloalkyl-silane esters of formula (I) comprises catalysed reaction of unsatd aliphatic cpds contg a reactive allyl (pseudo)halide gp and terminal double bond, of formula (II), with a hydridosilane ester of formula (III) in the presence of gp. VIII element and/or cpd. The novel features are that (a) a 0.1-0.0001 N soln or suspension of Ir and/or Ir cpds is prepd by stirring for at least 20 min with (II) alone or a mixt of (II) and (III) contg an excess of 0.01-100, pref 0.1-10 mole% (II) and opt in 5-95 wt% soln in inert solvents, eg hydrocarbons and/or (I); and (b) hydrosilylation is carried out with this at a catalyst concn of 10 - 10 mole%. R = 1-18C (halo)alkyl or (halo)cycloalkyl; R = R or H; R , R = R, H, aryl or halogen; R = 1-10C alkyl, opt contg aliphatic ether gps; X = F, Cl, Br, I, CN, NCO, NCS or N3; n = 0, 1 or 2.

    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: In the prepn. of aminopropylalkoxysilanes of formula (I) by reacting hydridosilanes of formula (II) with an amine of formula (III) in the presence of a Rh-complex catalyst with organo-P ligands, the catalyst comprises a moulded polymeric Rh complex catalyst (IV) with organosiloxane monophenylphosphine ligands: R R NCH2CHR CH2Si(OR)3-n(R )n (I) HSi(OR)3-n(R )n (II) R R NCH2CR =CH2 (III), R, R = 1-8C alkyl; n = 0, 1 or 2; R , R = H, 1-8C alkyl and/or 3-8C omega -alkenyl; R = H or 1-8C alkyl. Also claimed is the use of (IV) in the prepn. of (I).
