    • The invention relates to an aqueous emulsion of one or more polymers that is stable in storage and is composed according to general formula (I). In said formula: R 1 represents an unbranched or branched alkyl group or alkoxy group comprising between 1 and 4 carbon atoms; R 2 and R 3 independently of one another represent an unbranched or branched alkyl group comprising between 1 and 4 carbon atoms; R 4 and R 6 independently of one another represent bivalent organic compound groups; R 5 represents a hydrophobic, bivalent polymer group; and R 7 represents a CH 2 SiR 1 (OR 2 )(OR 3 ) group, in which R 1 , R 2 and R 3 are defined as above, or R 7 represents a group, which enables the polymer of general formula (I) to emulsify in water, forming an oil-water emulsion. According to the invention: the emulsion has a pH-value of between 2 and 11 and a solid content of between 40 and 95 wt. %, (in relation to the total weight of the emulsion) and contains one or more anionic and/or non-ionic emulsifiers, which are capable of forming an oil-water emulsion; if R 7 represents a group that enables the polymer of general formula (I) to emulsify in water, forming an oil-water emulsion, at least part of the emulsifier or emulsifiers are substituted by polymers of formula (I), said emulsion being obtained by the addition of the aqueous emulsion fractions to a mixture consisting of the emulsifier(s) and the polymer(s) of general formula (I). The invention also relates to a method for producing said emulsions, to the use of the emulsions as adhesives, caulking compounds, surface coating materials and polymer moulding compounds.
