- the compounds (2) are preferably used without prior conversion of the amino groups by means of protective group reagents such as aldehydes or ketones. They preferably contain at least one prim. Amino group. Examples of this are the amino methyl or the aminopropyl group. If the aminosilicon compounds (2) from "diamino" -
- Monomers such as aminoethylaminopropyl or aminoethylaminoisobutylsilanes produced contain these per prim.
- Amino group a sec. Amino group bound to the same Si atom. Prefers but the prim reacts.
- the compound (2) preferably contains an amine group concentration in the range from 0.01 to about 10 meq / g, particularly preferably from about 0.05 to 5 meq / g.
- Preferred viscosities are in the range from approximately 100 to 100,000 mPa's at 25 ° C., the range 500 to 50,000 mPa's being particularly preferred.
- the org. Compound (3) can be used as a reactant for the amino silicon compound (2) in two tautomeric forms which correspond to the formulas (II) and (III).
- This compound is obtained by reacting the basic compounds (E 2 ) x ZY (4) on which the free valences are saturated with hydrogen, with diketene, acetyketene, alkyl diketene, diketene-acetone adduct or also acetoacetate according to reactions known in the literature .
- the reaction with diketene or its acetone adduct is preferred.
- the radical “Z” is an organic radical which, due to its bi- to hexafunctionality, is linked to 2 to 6 further groups.
- the sum of “E” plus “Y” corresponds in numerical value to this functionality "Z” is bifunctional.
- “Z” is bound to either two Y groups or one Y group and a monofunctional end group.
- Monofunctional end groups can be saturated or unsaturated hydrocarbon radicals, or also acyl radicals such as the acetate, butyrate, palmitate or stearate radical , as well as the acrylate, methacrylate or benzoate residue.
- the remainder “Z” has a heteroatom content of at least 10% by weight.
- the heteroatoms are selected from the group of 0, N, B, P and S atoms; preferably 0- / N atoms, especially O - Atoms.
- the remainder “Z” has the task of adding higher polarity and thus a higher degree of hydrophilicity to the compounds (1) to introduce, which is why a higher content of heteroatoms is preferred.
- the radical "Z” is particularly preferably a polyether or polyester.
- Tri- to hexafunctional residues "Z” are normally started by alcohols which are as functional as by amines.
- Trimethylolpropane or ammonia with ethylene oxide provides base compounds (4) with "Z" of the general formula C 2 H 5 C (CH 2 (OC 2 H 4 ) n / 3 ) 3 or N (C 2 H 4 (OC 2 H 4 ) n _ 3/3 ) 3 , the free valences of which are linked to oxygen atoms (Y), which in turn are saturated with hydrogen.

- Corresponding polyesters can be prepared from the same or similar starter compounds by ring-opening polymerization of cyclic esters (lactones) by generally known methods.
- Preferred base compounds (4) are polyethylene glycol, polypropylene glycol and their copolymers, and their monoalkyl ethers. The latter are a special case with "Y" being oxygen and "E” being an alkyl group (methyl, alkyl, butyl). With regard to the conversion to compounds (3), these compounds (4) are monofunctional. Compared to the aminosilicon compounds (2), the compounds (3) produced therefrom are also monofunctional and accordingly serve to saturate amino groups with polar polymers.

- reaction of the compounds (3) with (primary) aminosilicon compounds (2) to give the ⁇ -ketoenamines (1) according to the invention proceeds spontaneously even without external heating, but the addition of heat has an accelerating effect on the synthesis of (1).
- the compounds (2) and (3) can be combined with one another and reacted within wide limits.
- a stochiometric excess of ⁇ -ketocarbonyl groups (or their enol tautomer) in relation to amino groups naturally leads to products which contain excess ⁇ -ketocarbonyl groups and vice versa.
- a stochiometric ratio of ⁇ -ketocarbonyl groups to prim is preferred.
- Amino groups from 0.8 to 1.2, particularly preferably from 0.9 to 1.1, are used.
- the molar ratio of the reacting groups can vary from about 0.1 to about 10.
- the reaction temperature amounts to preferably from 0 to approximately 140 0 C, particularly preferably 20 to 100 0 C.
- the surrounding pressure is not critical.
- the reaction under normal pressure or vacuum is preferred. If the water of reaction is removed in vacuo, this usually leads to an increase in the reaction rate. Even in cases in which the reaction water is not completely soluble in the product, it is advantageous to remove it, since clear products are obtained.
- Example 1 serve to further explain the invention.
- Example 1
- Example 2 Carried out analogously to Example 1, but instead of the 125 g of the aminosiloxane from Example 1, 47 g of a telechelic aminosiloxane consisting of 3- (aminoethylamino) propyldimethylsiloxy and dimethylsiloxy units with the amine number 0.78 are used.
- the mixture with an identical amount of the acetoacetate is also initially very cloudy, but it clears towards the end in the case of a weakly exothermic reaction. The reaction is complete after about 24 hours without external heating, which is confirmed by the 1 H-NMR spectrum.
- the structural element between polyether and siloxane corresponds to that of the copolymer from Example 1.
- Example 6 The product from Example 5 contains final ⁇ -
- Example 7 As in Example 5, bisacetoacetate is prepared from 97.7 g of dewatered polyethylene glycols with an average of 44 ethyleneoxy units and 9.0 g of diketene and excess diketene is removed. 385 g of the aminopropyl PDMS (200 mEqu.NH2) used there are metered in with vigorous stirring. After 2 hours at 50 0 C is obtained from the milky mixture only a slightly cloudy, yellowish oil, whose 1 H-NMR spectrum shows no signal for the acetoacetate more. Instead, the structural element identical to the product from Example 6 can be confirmed using the CH3 peak.
- the copolymer contains excess aminopropylene end groups in a concentration of 0.20 mEqu./g.
- Example 8 The copolymer contains excess aminopropylene end groups in a concentration of 0.20 mEqu./g.
