Abstract: The present invention provides polishes for surfaces, comprising aminoorganopolysiloxanes (A) which are solid at room temperature, contain fluoro groups and are able to change their aggregate state reversibly as a result of changes in temperature.

Abstract: 1,3-dihalo-1,1,3,3-tetra(organyl)disiloxanes of the general formula XR2Si—O—SiR2X  (1) are prepared by reacting hydrogen halide with the corresponding 1,3-dihydro-1,1,3,3-tetra(organyl)disiloxanes of the general formula HR2Si—O—SiR2H  (2), in which R is an alkyl or halogen substituted alkyl group and X is halogen, in the presence of a catalyst selected from transition metals of the 8th subgroup of the periodic table of the elements, or compounds or complexes of these transition metals.

Abstract: A process for the preparation of halogenated 1,2-disilaethanes of the general formula X3−nRnSi—CHR1CHR1—SiRnX3−n  (I) in which R may be identical or different and denotes a hydrogen atom or a monovalent optionally substituted hydrocarbon radical having 1 to 40 carbon atom(s) per radical, R1 may be identical or different and denotes a hydrogen atom or a monovalent optionally substituted hydrocarbon radical having 1 to 40 carbon atom(s) per radical, X denotes a halogen atom and n denotes 0, 1 or 2, wherein halogenated 1,2-disilaethenes of the general formula X3−nRnSi—CR1═CR1—SiRnX3−n  (II) in which R, R1, X and n have the meaning stated above therefor, are reacted with hydrogen in the presence of promoting catalysts. The product is produced in high yield and purity.
