Aqueous, storage-stable emulsions of α-silyl terminated polymers are useful as adhesives, sealing compounds and coating materials. The α-silyl terminated polymers correspond to the general formula (I):
in which R
1
is a linear or branched alkyl or alkoxy group containing 1 to 4 carbon atoms, R
2
and R
3
independently of one another are linear or branched alkyl groups containing 1 to 4 carbon atoms, R
4
and R
6
independently of one another are divalent organic connecting groups, R
5
is a hydrophobic divalent polymer group; and R
7
is a CH

) group, in which R
1
, R
2
and R
3
have the above meaning or R
7
stands for a group that lends the polymer of the general formula (I) the property of self-emulsification in water by forming an oil in water emulsion.
