1. A compound having guanidine groups and containing semi-organic silicon groups, of the formula (I):
MaMGbDcDGdTeQf (I); where:
a =0 to 10;b =0 to 10;c =0 to 350;d =0 to 50;e =0 to 50;f =0 to 10;where the sum of the indices b and d is greater than or equal to 1 to 20;with the proviso that:
when the index a is 2 and at the same time the sum of the indices b, c, e, and f is zero, the index d is other than 1; orwhen the sum of the indices a, c, d, e, and f is zero, the index b is 2; and where:
M=[R3SiO1/2];MG =[RGR2SiO1/2];D=[R2SiO2/2];DG =[RG2SiO2/2];T=[RSiO3/2];Q=[SiO4/2];R are, independently of one another, identical or different and are OR2 groups and/or linear or branched, saturated or else mono- or polyunsaturated hydrocarbon radicals, which may be interrupted by heteroatoms and/or may be substituted one or more times by hydroxyl, amino, carboxyl or aryl radicals;
where Ra is identical or different and is hydrogen and/or alkyl groups having 1 to 12 carbon atoms; andRG is a radical containing guanidine groups and selected from the group consisting of the formulas (IIa), (IIb), and (IIc), and tautomers and salts thereof: where:
R3 are divalent radicals which, independently of one another, are identical or different, linear or branched hydrocarbon radicals containing 1 to 50 carbon atoms, and may be interrupted by heteroatoms, and/or which may be substituted one or more times by hydroxyl or amino radicals; andR11, R12, R21, R22, and R31 are, independently of one another, identical or different and are hydrogen, linear or branched or cyclic hydrocarbons containing 1 to 15 carbon atoms, it being possible for the hydrocarbons also to contain 1 or 2 heteroatoms, preferred heteroatoms being nitrogen, oxygen and silicon; wherein at least one RG in the formula (I) is of the formula (IIa) or (IIb). |
