Moisture-curing compositions comprising (a) polymers with alkoxysilane end groups and (b) reaction products of primary aminosilanes with mono-, di- or tri-substituted ethylene or optionally substituted maleimide, in which the substituents are selected from cyano, alkoxycarbonyl, amido, nitro, phosphonic acid or ester, and sulphinic or sulphonic acid or ester. Moisture-curing compositions (MCC) comprising (a) silane-functional polymer(s) (P) with end groups of formula (I) and (b) reaction product(s) (R) of aminosilane(s) (A1) containing at least one prim. amino group with silane group-free alkene(s) (M) of formula (II), (III) or (IV). R 1>1-8C alkyl, especially methyl or ethyl; R 2>1-5C acyl or alkyl, especially methyl, ethyl or isopropyl; R 3>optionally cyclic 2-12C alkylene, optionally with aromatic parts and optionally with hetero-atom(s), especially nitrogen; a : 0, 1 or 2, preferably 0 or 1; R 9>R 12> or CN; R 10>COOR 12>, CONHR 12>, CON(R 12)> 2, CN, NO 2, PO(OR 12>) 2, SO 2R 12> or SO 2OR 12>; R 11>R 12>, COOR 12>, -CH 2COOR 12> or CN; R 12>H or 1-20C hydrocarbyl, optionally with hetero-atoms . Independent claims are included for (1) a method for sealing by placing MCC between two substrates S1 and S2 (same or different) and then curing the MCC by contact with moisture (2) a method for adhesive bonding by placing MCC between substrates as above, bringing the parts together within the open time and then curing as above (3) sealed or glued articles obtained by these methods .
