Curable electron donor compositions
View Patent ↗Electron donor compounds, suitable for use as adhesives or as components in adhesives, contain a carbon to carbon double bond attached to an aromatic ring and conjugated with the unsaturation in the aromatic ring.
1. A composition comprising a conductive or non-conductive filler and a compound having the structure:
in which
n is 1;
Ar is an aromatic or heteroaromatic ring or fused ring having 3 to 10 carbon atoms within the ring structure, in which the heteroatoms may be N, O, or S;
R 1 , R 2 , and R 3 are independently hydrogen, an alkyl group having 1 to 12 carbon atoms, or Ar as described above;
G is —OR 4 , —SR 4 , —N(R 1 )(R 2 ), Ar as described above, or an alkyl group having 1 to 12 carbon atoms, in which R 1 and R 2 are as described above and R 4 is Ar as described above or an alkyl group having 1 to 12 carbon atoms;
Q is an alkyl group having 1 to 12 carbon atoms;
X is
and Z is an alkyl group, a siloxane, a polysiloxane, a C 1 to C 4 alkoxy-terminated siloxane or polysiloxane, a polyether, a polyester, a polyurethane, a poly(butadiene), or an aromatic, polyaromatic or heteroaromatic group.
