    Abstract: Moulded articles of polyolefins are dyed or printed with water-insoluble dyes that are soluble in organic solvents from aqueous dispersion or organic solution with either simultaneous or prior treatment with a dispersion or solution of a silicon hydrocarbon compound, an alkysiloxane, arylsiloxane, alkylarylsiloxane, alkylpolysiloxane, arylpolysiloxane, alkylarylpolysiloxane or an ester or polyester of silicic acid which silicon compounds are soluble in hydrocarbons. In Example 6 moulded articles of polyethylene are dyed with an aqueous liquor containing polydimethylsiloxane, a dispersed anthraquinone dye and surfactants and in Example 7 the same articles are printed with a solution in methylene chloride of hexyl-azo-naphthalene, tetraethylsilicate, nickel - II - oleate, triethanolamine and a linear polymer from ethyltriethoxysilane (80%) and phenyltriethoxysilane (10%).ALSO:Polyolefin materials are dyed or printed with water-insoluble dyes, which are soluble in organic solvents, from aqueous dispersion or organic solution in a process wherein the material is pretreated with a dispersion or solution of a silicon hydrocarbon compound, an alkylsiloxane, arylsiloxane, alkylarylsiloxane, alkylpolysiloxane, arylpolysiloxane, alkylarylpolysiloxane or an ester or polyester of silicic acid which silicon compounds are soluble in hydrocarbons, or wherein the dyeing or printing is carried out with the co-employment of any of the said silicon compounds. The so-treated material may then be subjected to a heat treatment. The polysiloxanes may be formed in situ with the help of catalysts, e.g. acids, bases or metal salts. The preferred polysiloxanes cross-link when the dye is fixed, again preferably in the presence of metal salts. Examples are given.

    Abstract: Concrete compositions are prepared from cement, water, an optional aggregate and particles of expanded styrene polymers whose surfaces are coated with an organosiloxanol of formula where n is an integer from 1-250, R is a C1-C6 alkyl or alkenyl group or an aryl group. The styrene may be copolymerized with acrylonitrile, acrylic or methacrylic esters of C1-C8 alcohols, N-vinyl compounds, e.g. N-vinyl carbazol and divinylbenzene. Aggregates specified are sand, pumice, vermiculite and asbestos.

    Abstract: Silanes are prepared by reacting at 220 DEG C. or less, finely-divided silicon in the liquid phase with an alcohol or phenol in the absence of alkaline catalysts, if necessary in the presence of a liquid organic diluent or a liquid Si-compound. By "silanes" is meant compounds containing at least one Si-H bond; by "finely-divided" is meant Si of 80-99% purity and of particle size 100-0.1 m . Preferably oxygen is excluded from the reaction mixture, e.g. by nitrogen. Soluble (in the reaction medium) Cu and Zn salts may be added as accelerators. The products are mono- or polymeric, e.g. up to 30 recurring units and may also be cyclic.ALSO:Monosilane is a by-product in the reaction of finely-divided Si in the liquid phase with an alcohol or phenol at 220 DEG C. or less in the absence of alkaline catalysts, and if necessary in the presence of a liquid organic diluent or liquid Si compound. The main products, e.g. of the type SiH2(OR)2, where R is substituted or unsubstituted alkyl or aryl, disproportionate to monosilane and Si(OR)4.
