    Abstract: NOVEL CYCLIC THIOUREA DERIVATIVES CONTAINING SILICON ATOMS HAVE THE GENERAL FORMULA
    WHEREIN R IS A HYDROCARBON RADICAL OPTIONALLY BEING INTERRUPTED BY OXYGEN ATOMS IN ETHER LINKAGES, R'' AND R" (SAME OR DIFFERENT) ARE HYDROCARBON RADICALS, HALOHYDROCARBON RADICALS, CYANOHYDROCARBON RADICALS, OR ALKOXY RADICALS, AND R''" IS A HYDROCARBON RADICAL. THE COMPOUNDS ARE USEFUL AS CROSS-LINKING AGENTS AND AS INTERMEDOATES FOR CARBOFUNCTIONAL SILOXANES. THESE 2,5-DIAZA-3-SILACYCLOPENTATHIONES CAN BE PRODUCED, ACCORDING TO THE INVENTION, BY REACTING AN AMINOMETHYLALKOXYSILANE OF THE GENERAL FORMULA

    R"''-NH-CH2-SI(-R'')(-R")-O-X

    (R'', R" AND R''" AS ABOVE; X =ALKYL) AT A TEMPERATURE BETWEEN 0 AND 250*C. WITH AN ISOTHIOCYANATE OF THE GENERAL FORMULA RNCS (R AS ABOVE) AND RECOVERING THE PRODUCT BY DISTILLATION UNDER REDCUED PRESSURE OR BY FILTRATION. THESE PRODUCTS ARE SUITABLE AS INTERMEDIATES FOR CARBOFUNCTIONAL ORGANOPOLYSILOXANES AND AS CROSS-LINKING AGENTS IN WATER-REACTIVE ORGANOPOLYSILOXANE PREPARATIONS.

    Abstract: New carbofunctional organosilanes which may be regarded as alkoxysilyl- and glycidyl ether-substituted carbamate-modified urea derivatives having the formula

    are obtained by reacting an aminomethyl-alkoxysilane of the formula

    with an epoxy-organo-isocyanate of the formula

    at a temperature below 50*C. In these formulae R is alkyl; R'' is alkyl, cyclohexyl or phenyl; R'''' is alkylene or cycloalkylene; n is 1, 2 or 3. The products are utilizable for priming silicious surfaces and for cross-linking convertible organopolysiloxanes.
