Curable polymer compositions comprising heteroatom-containing silane compounds

A curable composition comprising

• (A) at least one curable polymer;
• (B) at least one silane compound of general formula (I) containing at least one heteroatom bridged to a silicon atom via a sp2-hybridized quaternary carbon atom
• wherein
• n is 1, 2 or 3;
• m is 1 or 2;
• k is 0 or 1, wherein the sum of n, m, and k is 4;
• and
• q is an integer selected from 0 to 3;
• each R1 is independently selected from a hydrolyzable group,
• each R4 is independently selected from hydrogen or a linear or branched, substituted or unsubstituted hydrocarbon group having 1 to 20 carbon atoms which optionally contain at least one heteroatom;
• X is a divalent or polyvalent heteroatom;
• each R5 is independently hydrogen, or a linear or branched, substituted or unsubstituted hydrocarbon group having 1 to 20 carbon atoms which optionally contain at least one heteroatom;
• R2 is a linear or branched, substituted or unsubstituted hydrocarbon group having 1 to 20 carbon atoms which optionally contain at least one heteroatom,
• R3 is hydrogen or a linear or branched, substituted or unsubstituted hydrocarbon group having 1 to 20 carbon atoms which optionally contain at least one heteroatom, or R2 and R3 combine to form a cyclic structure;
• and
• (C) optionally at least one curing catalyst.
