    Abstract: NEW ORGANOSILOXANE- AND CARBAMATE-MODIFIED UREA DERIVATIVES COMPRISE AT LEAST ONE STRUCTURAL UNIT OF THE FORMULA

    (O(3-M/2)-SI(-R'')M-CH(-R")-N(-R"'')-CO-NH-Q-NH-COO-(CNH2N-

    O)B)C-Q

    AND OPTIONALLY FURTHER STRUCTURAL UNITS OF THE FORMULA

    (R'')A-SI-O(4-A/2)

    WHEREIN HOWEVER AT LEAST ONE OF A THOUSAND STRUCTURAL UNITS CORRESPONDS TO THE FIRST OF THE ABOVE FORMULAE. IN THESE FORMULAE R'' IS A M ONOVALENT HYDROCARBON RADICAL, R" AND R" ARE HYDROGEN ATOMS OR MONOVALENT HYDROCARBON RADICALS, Q'' IS A BIVALENT HYDROCARBON RADICAL, Q IS A MONOVALENT TO HEXAVALENT HYDROCARBON RADICAL, M IS 0, 1 OR 2, N IS 2, 3 OR 4, A IS 0, 1, 2 OR 3, B IS ZERO OR AN INTERGER FROM 1 TO 200, AND C IS THE VALENCY NUMBER OF Q. THESE UREA DERIVATIVES ARE PREPARED EITHER BY HYDROLYZING A CORRESPONDING ALKOXYSILYL-SUBSTITUTED CARBAMATEMODIFIED UREA DERIVATIVE, OPTIONALLY IN ADMIXTURE WITH HYDROCARBON-SUBSTITUTED ALKOXYSILANES, OR BY REACTING A CORRESPONDING AMINOLKYL-SUBSTITUTED POLYSILOXANE WITH AN ISOCYANATE-MODIFIED CARBAMIC ACID ESTER OF THE FORMULA

    (O-CN-Q''-NH-COO-(CNH2N-O)B)C-Q

    THE PRODUCTS ARE TO BE USED AS PRIMING AGENTS IMPARTING ADHESION TO SYNTHETIC RESINS ON SILICEOUS SURFACES, AS SURFACTANTS AND AS INTERMEDIATES FOR ORGANO-POLYSILOXANE RESINS.

    Abstract: The invention comprises compounds of the formula where R4, R5 and R6, which may be the same or different, represent alkyl radicals which may be interrupted by ether oxygen atoms, aryl radicals, cycloalkyl radicals or aralkyl radicals, at least one of which radicals is substituted by an isocyanate group, which radicals may be further substituted by other groups. The compounds are prepared by reacting an amine of the formula or the hydrochloride or carbamate thereof, in which R1, R2 and R3, which may be the same or different, represent alkyl radicals which may be interrupted by ether oxygen atoms, aryl radicals, cycloalkyl radicals or aralkyl radicals, at least one of which radicals is substituted by a primary amino group, which radicals may be further substituted by other groups, with phosgene. Specified substituents include chlorine and bromine and thioether, nitrile, sulpho, sulphonic acid ester, carboxylic acid ester, alkoxy, phenoxy, sulphene and further carbamate groups. Phosgenation is effected by known methods, e.g. the cold phase-hot phase process. A reaction solvent may be used. The amino urethane reactants may be prepared by reduction of the corresponding nitro-, cyano- or carbamoyl-urethanes.
