    • The present invention relates to a composition which comprises (i) at least one block condensate of organofunctional siloxanes of the general formula (I) [F]e[QcPb]d (I) and/or (ii) at least one mixture composed of e[F] and d(c[Q]+b[P]) and, where appropriate d[QcPb]. These compositions or block condensates are obtainable via reaction of block units F with block units Q, P, and/or QP, by one of the following methods:—c1) diluting block unit F optionally with an alcohol, adding an organic or inorganic acid and from 0.5 to 150 mol of water per mole of Si of the siloxane used, whereupon at least partial hydrolysis of the block units used takes place, then adding block unit Q and block unit P, and allowing the mixture to react, or—c2) diluting block unit F optionally with an alcohol, mixing with Q, P, and/or block unit QP, then adding an organic or inorganic acid and, using from 0.5 to 150 mol of water per mole of Si of the siloxanes used, carrying out partial hydrolysis and block-condensation, or—c3) diluting block unit F optionally with an alcohol, adding an organic or inorganic acid and from 0.5 to 150 mol of water per mole of Si of the siloxane used, with at least partial hydrolysis, adding block unit QP, and allowing the mixture to react, or—c4) diluting block units Q, P, and/or QP, optionally with an alcohol, adding an organic or inorganic acid and from 0.5 to 1.5 mol of water per mole of Si of the siloxanes used, and at least partially hydrolyzing, then adding block unit F and also from 0 to 148.5 mol of water per mole of Si of the siloxanes used, and allowing the mixture to react, or—c5) diluting block unit F optionally with an alcohol, mixing with from 0.5 to 150 mol of water per mole of Si of the siloxanes used, and with an organic or inorganic acid, and then adding a tetraalkoxysiloxane, and allowing the mixture to react. The present invention further relates to a process for the preparation of these compositions or block condensates, and to their use and to items thus obtainable: abrasion-resistant easy-clean coatings and items equipped with this type of coating.

    • A process for preparing an alkylaminoalkylalkoxysilane of formula (I) R—(NR′)—Y—Si(R1)n(OR2)3-n (I) in which R is a linear, branched or cyclic alkyl group having 1 to 12 carbon atoms, R′ is a hydrogen (H) or is a linear, branched or cyclic alkyl group having 1 to 12 carbon atoms, Y is a bivalent alkyl group from the group of —CH2—, —(CH2)2—, —(CH2)3—, —(CH2)(CH(CH3))(CH2)— and —(CH2)4—, R1 and R2 groups are the same or different and are each a linear or branched alkyl group having 1 to 4 carbon atoms, and n is 0 or 1 or 2, by reacting an alkylamine, used in excess, with a haloalkylalkoxysilane, distilling off excess free alkylamine, treating the remaining product mixture with the alkylaminoalkylalkoxysilane and working up.
