Moisture-curing compositions containing silane-functional polymers and aminosilane adducts with good adhesive properties

A moisture-curing composition comprising

• a) at least one silane-functional polymer P having at least two end groups of the formula (I)
• where
• R1 is an alkyl group having 1 to 8 C atoms;
• R2 is an alkyl group having 1 to 5 C atoms;
• a is 0, 1 or 2;
• and
• X is a divalent radical selected from the group consisting of —NH—CO—N(R3)—, —NH—CO—S—, —NH—CO—O—, —O—CO—NH—, —N(R3)—CO—NH—, and —S—CO—NH—, where R3 is a hydrogen atom or is a linear or branched hydrocarbon radical having 1 to 20 C atoms which optionally contains cyclic fractions and which optionally has at least one functional group selected from the group consisting of alkoxysilyl, ether, sulfone, nitrile, nitro, carboxylic ester, sulfonic ester, and phosphonic ester;
• b) at least one reaction product R prepared from
• at least one aminosilane AS having at least one primary amino group, and
• at least one silane-group-free alkene M which is capable of undergoing 1,4-addition reactions with primary amino groups.
